Update: 21st of May, 8:00 a.m. UTC

After hammering India and Bangladesh, Amphan is forecasted to move north-northeastward and weaken into a depression later today. The maximum sustainable winds, which may be carried by the storm, are 50 km/h (27 KT).

Thunderstorms with gusty winds are likely to occur over Bihar and isolated places such as Assam, Arunachal Pradesh and Meghalaya.

Due to the correct timing of rescue teams deployment, there is a minimum human loss.
The worst damages has been concentrated in the West Bangal districts and Sunderbans, which suffered immense destruction.

Update: 20th of May, 4:00 p.m. UTC

The super cyclone Amphan hits India and Bangladesh with its landfall between Indian town of Digha and Hatiya Islands in Bangladesh. Storm is dumping heavy rain and damaging winds on Kolkata leaving a trails of destruction. Reported damages are destroyed houses, power cuts and downed trees.

Cyclone is now moving at 31km/h (17 KT) near 22.2N 88.3E, roughly 25 NM from Kolkata with maximum sustainable winds 138 km/h (75 KT) and gusts 166 km/h (90 KT).

Amphan will move north-northeasterly passing trough the Sunderbans and gradually weaken.

Update: 20th of May, 8:00 a.m. UTC

TC Amphan was moving at 25 km/h (14 KT) near 20.5N 87.9E approximately 129 NM South-Southwest of Kolkata in the last 6 hours. Maximum sustained winds were 157 km/h (85 KT) and gusts 194 km/h (105 KT), which makes it a Category 2 Atlantic hurricane and the strongest storm ever recorded in the Bay of Bengal.

Anticipated landfall still remains for Wednesday evening hours local time (5:30 pm Wednesday IST) near or just east of Hooghly River south of Kolkata.

Impacts

Cyclone could bring very strong storm surges up to 5 meters (16.4 feet), causing roadblocks, power link outages and destruction of houses and crops.

Evacuation of people continues, but a pandemic situation puts a great stress on the whole operation as it became difficult to maintain social distancing.

Update: 19th of May, 02:00 p.m. UTC

Super cyclone Amphan has been already marked as extremely intense in the region and the second strongest storm since 1999. Cyclone is due to make the landfall into West Bengal, Digha and Hatiya Island in Bangladesh during Wednesday morning.

Reading the latest news, everybody has to be concerned about the Coronavirus and its impact on daily life of billions of people. The Coronavirus (virus is officially labeled as SARS-CoV-2 and its disease as COVID-19) is spreading quickly around the world, causing unprecedented lockdowns of huge regions and cities, havoc on markets and overload of health facilities in affected areas.

Some countries seem to have already contained the major spread of virus (China, South Korea), some are currently experiencing the initial extreme increase of patients with severe cases (Italy, Iran), with the rest of the world expecting it in upcoming weeks and trying to prepare for it.

Question is, will the rate of spread slow down or even disappear at all? It definitely will.

Check this nice video demonstrating the principle of exponential growth and epidemics

It’s essential to understand that even a very small decrease in “probability of exposure becoming an infection” (referred as p in the video) can reduce the growth of the spread significantly or even stop it completely.

But why do we discuss it at Windy.com, we normally talk just weather, right?

The reason is the outside temperature. Spread of typical flu highly correlates with weather, having its season peak in cold months, declining during spring with almost no cases during the warmest part of the year. Recent studies show that high temperatures and especially high humidity slows the influenza spread. More moisture in warmer air behaves as a barrier for airborne viruses so droplets of cough or sneeze cannot travel as far as they would in colder, dry air.
Of course, more factors can play a role in this flu seasonality (longer sunlight exposure, less clustering of people indoors), but temperature is considered as the major one.

There is a whole family of coronaviruses, some of them already known to humans, causing mild colds and behaving similar to the flu - in warmer climate, they tend to decline. That is the reason why many people believe that same will happen with COVID-19. As stated above, even the slight decrease in person to person transfer rate of the virus has a huge impact on overall number of cases. Will a higher temperature and humidity help us in this way? There are many opinions on that subject, but most experts agree, that it’s too early to judge and only hard data from summer season and their detailed analysis will tell us the truth.

But until then, we have no other option than to make assumptions based on data we have now.

Posts discussing weather patterns (temperature/humidity):

The perspective

As mentioned, the COVID-19 is not all that unknown to us, we had coronavirus strain SARS back in 2003. SARS had its peak in winter months and faded away during May. Typically influenza season falls sometimes between the beginning of fall and the end of spring. So the SARS did not really exceed the usual influenza season trend. But can we expect COVID-19 to follow this path as well?

The current spreading rate tells us a fact, that the COVID-19 has more incidences in places with dryer and colder environment than in more humid and warm locations. For instance let´s take a look at Japan, we would expect the virus to be spreading mainly in big cities like Tokyo, due to a number of foreign visitors and population. But this is not the case, COVID-19 is actually spreading in Hokkaido, despite it has a much lower frequency of travellers. However the weather conditions there are favorable, dry and less humid environment. The same goes for Italy and its epicenter Milan. North of the country is significantly more affected than the south.

On the other hand, it would not be wise to expect the novel coronavirus to behave as the ones before.
It is necessary to say, that SARS 2003 did not go away just because weather got warmer. It was followed by national interventions to isolate cases and everyone, who had the possibility to be infected.

We have already said that the environment plays a key role in influenza activity and dry/cold weather with low humidity favors the transmission. But influenza epidemics often appears in a tropical and subtropical regions during rainy seasons with obviously high humidity values. In other words, there are two types of influenza environments. In cold-dry environment, where humidity/temperature goes below 11–12 g/kg and 18–21°C, influenza peaks during cold months. In humid-rainy case, if humidity/temperature does not go under those values, influenza peaks during rainy season.

Immunity is another factor, which is worth a consideration. Our immunity is significantly worse in winter than in summer and we also lack vitamin D, because of less ultraviolet light exposure in cold months. Vitamin D benefits our immune system and helps us to be durable against numerous diseases, even so this factor can be observed as not so important in relation to influenza activity.

But then again, new viruses are likely to persist longer than a common ones, which have been in the population for years or decades.

Available data

We at Windy.com are no experts in the area of viruses, but we have access to the best weather data available.

We have assembled temperature records for each country (taken from the area of major spread of the virus within the country or the capital of that country) and pictured them along with recent Coronavirus spread data (daily amount of new cases, sourced from Coronavirus COVID-19 Global Cases by Johns Hopkins CSSE) to see if there could be any correlation.

Based on the charts above, we can see a slight correlation in relation with a higher temperature and virus decrease, and opposite a lower temperature and faster spread of COVID-19.

Of course, there are many drawbacks in this approach:

• data coming from different countries aren’t easily comparable (some countries test much more than the others, some have much highly populated areas, also quality of data coming from some countries is more than questionable)

• the virus has quite a long incubation period, therefore “new” cases are being reported several days after the people were actually infected (but at least average temperature at given location can help to mitigate this effect)

• there are still not that many daily observations, the data window is quite too small

• correlation does not imply causation” - even if there seems to be a visual dependency between the temperature and the increase/decrease rate of new cases, it is absolutely no proof that there is a correlation between those two

As always there are many opinions and very little data to predict anything for sure. So the truth will be somewhere in the middle. It should be essential to avoid any catastrophic predictions as well as not to underestimate it.

The latest data for China shows a retreat of Coronavirus cases and high amount of recovered patients in a comparison to the total amount. Other countries will hopefully have the same progress.

Not happy with the findings? Don’t despair. If the weather won’t help us, there are still many ways, how each of us can help - avoid crowded places, work remotely if possible, stay fit, wash your hands, do not touch your face.
Avoid face to face social contacts for a while - read a couple of books or go online! There is still a lot to explore, also at Windy.com.

We are proud to strengthen our partnership with The Copernicus Atmosphere Monitoring Service (CAMS) with 3 new CAMS layers being implemented on Windy.com. The official press release from Copernicus here.

Our ongoing partnership since 2019 has already brought visualization of several CAMS layers and empowering general public to observe climate changes at a global scale.

From now on, users can access CAMS data via three new layers: fire intensity, surface ozone and total column sulphur dioxide (SO2). The overal objective is to rise awareness of air pollution and provide air quality data in easy and understandable way.

“We are delighted to be working with Windy to integrate CAMS data, so that its many users can access our global and European-scale forecasts,” says Vincent-Henri Peuch, Director of CAMS.

“If air quality forecasts were as common as weather forecasts it would help inform the public and make people more aware about the need to combat air pollution. The way that Windy visualises CAMS data helps people to understand that air pollution is not simply a local problem, but can be transported hundreds or thousands of kilometres by winds. Using Windy, users can easily follow where air pollution is transported and where it accumulates.”

Surface ozone

Ozone is formed in the lower atmosphere through chemical reactions triggered by sunlight involving nitrogen oxides and volatile organic compounds.

Ozone is generally highest in spring and summer, downwind of areas with high levels of emissions. It is a toxic gas that causes cardiopulmonary and respiratory problems, and can affect crop yields, so being aware of local levels can be vital.

Total column Sulphur dioxide (SO2)

Sulphur dioxide is emitted from several sources, including volcanic eruptions and combustion of unrefined fossil fuels. This layer will show the amount of sulphur dioxide from the ground to the top of the atmosphere.

Fire intensity

This layer uses coloured pixels to indicate active fires. Thermal radiation from actively burning vegetation (including wildfires and agricultural open burning) is related to the rate at which fuel is being consumed and smoke produced, and so are also linked to emissions of trace gases and small airborne particles.

And it truly was.. Windy team once again went on an adventure, and this time we decided to conquer Norway and its snowy hills covered with picturesque cottages.

Our journey started on Prague’s airport, where we had a flight to Oslo and from there we took a long ride by car (5,5 hours) until we arrived in Ustaoset, Buskerud, where we stayed for a week on our colleague’s cottage. (Many thanks again to Honza for the invitation and the hospitality!).

There was really no shortage of snow. Ustaoset is 990m above the sea level and is the finish spot for the cross country ski event Skarverennet. So the scenery was great and view from cottage’s living room, even better.

Due to coming storm Dennis the weather was not ideal especially in the beginning of our week. So the first day we spent working and making plans for the upcoming days.

When the weather got better, there was a plenty of options what we could do!

Kiting

Probably the most tempting activity we all wanted to try was snowkiting. 
Since most of us are complete beginners, we had our instructors nearby to teach us the basic techniques to operate the kite and help us. 

Kiting is certainly not one of the easiest sports you can do, in the beginning, you spend quite a bit of time untangling your kite, because it tends to get out of control a lot and you have to put it in the air over and over again.
It frankly requires a bit of patience, but once you get into it, you will love it. 

It was a great feeling to chase winds on a snowy plains either on skies or snowboard.

A little different camping

Since we saw a chance to get the true nordic night experience firsthand, we took the challenge and a few of us decided to spend a night outside. 

We did have all the necessary equipment and experienced instructor to guide us through. So the fun could begin!

We had to start building two tents early in the afternoon to get things done in time. 
KP for aurora borealis was 4 at that time, so there was a little chance, but we still secretly hoped to catch it. 
A few hours later, the two tents were standing, tops of mountains started to get a pink tint and we were about to call it a day, cooked dinner and went to a bed early.

Nevertheless, since we know how to command weather, we did see aurora borealis in the end. 
In the morning, still in a shadow of the past night, green as an emerald, just as we all pictured it. :)

Skiing and the surprise

Norway has quite a few skiing resorts and the one we went to was Geilo. It happens to be the 5th best resort in Norway, located just a few kilometres from Ustaoset. The first impression was half empty slopes with a fresh powder snow, so actually really nice.

After we enjoyed a full day of sunny weather in the mountains, we joined an evening surprise, which was a night sledding and a hot bath outside for the more venturesome among us.

Here is a little sneak peek on how we pulled it off in the end:

Burevi has weakened as it moves across the southern tip of India. Currently located near 9.3N 79.6E, toward the west-southwest, the system is moving near 4 km/h (2 knots).

Maximum sustained winds are near 55 km/h (35 knots).

It is forecasted that Burevi will strengthen after it emerges into the Arabian Sea over the weekend.

Update: 3rd of December, 11.30 a.m. UTC

Tropical cyclone Burevi, located 9.2N 79.8E is moving near 16.6 km/h (9 kt). Maximum sustained winds are near 65 km/h (35 kt).

The system is moving over water that has favorable conditions, expected to intensify slightly before making landfall along the coast of southern India. Then it is forecasted for Burevi to begin to weaken as it moves over land. The system will then enter the Arabia sea.

Update: 2nd of December, 4:30 p.m. UTC

Tropical cyclone Burevi, the fifth cyclone in the North Indian Ocean this year, is located near 8.8N 82.3E and currently making landfall in Sir Lanka with maximum sustainable winds of 74 km/h (40 kt).

Cyclone is then expected to travel towards India and approaching the Tamil Nadu coasts Kanyakumari and Pamban on early December 4.

Heavy to extremely heavy rains are forecasted in Tamil Nadu and Kerala till December 5. However Burevi is expected to be the least destructive cyclone of this year.

SpaceX launch of NASA Astronauts is postponed over the weather

Thunderstorms and light rain caused by Tropical Storm Bertha were the reason why mission Commercial Crew Demo-2 was aborted only 17 minutes before liftoff.

The Next attempt is scheduled for Saturday, 30 May at 7.22 PM UTC (3.22 PM EDT).

Although chances for success look similar, stormy weather with cloud cover is predicted, upper winds, which can drive thunderstorms to the coast, might be better. On the day of supposed launch, upper winds were moderate (13 kt/24 km/h), on Saturday will be light (4kt, 8 km/h).

In case the launch will be postponed again, the backup launch window for Falcon 9 is available 31 May at 7 PM UTC (3 PM EDT), with the same probability for success.

Update: 27th of May 01:00 p.m. UTC

The SpaceX first-ever crewed spaceflight is scheduled to take off from Cape Canaveral in Florida later today as a mission Commercial Crew Demo-2.

The launch is currently set to 08:30 p.m. (4:33 PM EDT) from Kennedy Space Center, however the weather conditions are not looking very favorable. There is currently a 50% chance that clouds and stormy weather will delay the proceedings due to violating the safety guidelines.

The Crew Dragon capsule will initially spend 19 hours orbiting the Earth till reaching the International Space Station on Thursday.

If the launch ends up to be postponed, another opportunity to send the capsule into the orbit will be on Saturday 30th May.
