Všimnul jsem si toho před pár dny, a je to paráda, hlavně jak to krásně odděluje pevninu. Ještě by se mi líbil nějaký hybrid s IR ;-)
Congrats!
Today is the 51st Anniversary of the Hurricane Camille landfall in Mississippi on August 17, 1969.
Hurricane Camille made landfall late in the evening near Waveland, Mississippi. Combination of wind, surge, and rainfall resulted in 256 deaths (143 along the Gulf Coast and 113 in the Virginia floods).
Hurricane Camille path, timeline of the damage, in-depth description of the event, and also short fact-check of the often-publicized “hurricane party” story can be found in my Hurricane Camille article at Extreme Weather Club website.
Contact @Korina, she will help you with that
ECMWF/CAMS Forecasts of Aerosol Optical Depth for Sunday 23/02 at 1800 UTC (forecast based Sunday 23/02 at 0000 UTC) and for Friday 28/02 at 1500 UTC (forecast based Thursday 27/02 at 0000 UTC)
After desert dust grounded flights in the Canary Islands, forecasts from the Copernicus Atmosphere Monitoring Service (CAMS) can help track where the dust goes next to help both the transport industry and travellers
A large swathe of desert dust from the Sahara swept across the Canary Islands earlier this week, turning skies red and prompting travel chaos – and also causing extreme levels of particulate matter. The Copernicus Atmosphere Monitoring Service (CAMS) reveals how its forecasts help businesses and individuals plan against its impact. CAMS is implemented by the European Centre for Medium-Range Weather Forecasts on behalf of the European Commission.
CAMS is continually monitoring the movement of desert dust over the North Atlantic Ocean and the latest global and regional forecasts of aerosol optical depth and surface particulate matter (PM10) are predicting that it will travel across southern and western Europe in the coming days with impacts on air quality and a number of activity sectors, such as solar power generation across the Iberian peninsula.
By providing these forecasts of the amount and location of desert dust in the atmosphere, CAMS can help scientists, environmental agencies, energy and transportation companies, businesses and individuals make plans and mitigate its effects. It is not only transportation which can be affected by desert dust incidents, but particles from the plumes, which can often travel thousands of kilometres, can have health impacts.
Produced twice a day, forecasts take into account the emission, transport and deposition of the dust by combining satellite observations with a state-of-the-art computer model to accurately predict the amount of dust that is generated by surface winds and how the distribution of the resulting plumes will change over the next five days.
Greater knowledge of dust deposition can help organisations monitor air quality and also susceptible individuals who can change their plans or behaviour, such as not drying clothes outside or parking their car indoor if this is possible for them.
Vincent-Henri Peuch, Director of the Copernicus Atmosphere Monitoring Service, comments: “As we have seen from the incident affecting flights to and from the Canary Islands, dust particles can not only cause huge disruption, but affect people’s health as well. This is why it’s vital to have accurate forecasts and CAMS not only provide these, but work with companies and organisations which can relay this information to the public through smartphone or tablet apps and websites.”
“In fact, CAMS delivers forecasts of dust and of other key air pollutants to leading applications providing air quality information to the public such as Windy, BreezoMeter, Plumelabs and iPhone´s weather app powered by The Weather Channel, ” he added.
Each model has a different update and reference times and it could be confusing what connection does it have to actual update. Before we get to how often are the weather models updated and where to find the update/reference time on Windy, let's see what's the difference between the reference time and the update time.
Reference time is the time when a model starts a new forecast block. The process consists of the following:
For example model ECMWF has an update interval 12 hours, that means the first reference time will be 00:00:00Z (Zulu time) and second one 12:00:00Z.
Update time is time between the reference time and the actual update. The whole process of data computation takes approximately from 8 to 9 hours. For example the ECMWF model update times are 07:15:00Z and 19:15:00Z.
The table below describes when and how often are the weather models updated. All times are in UTC.
While on desktop, to get the reference and the update time, just click the clock icon in bottom right corner of the screen. In app, you have to dig deeper into the menu. See the screenshots below.

Sprawdzanie kamery pogodowej jest niezbędnym elementem każdej przygody.
A my w Windy jesteśmy zobowiązani do zapewniania coraz lepszych usług osobom takim jak my sami. Dla pilotów, kiterów, poszukiwaczy przygód, alpinistów i wszystkich dusz, które są raczej na zewnątrz niż w centrum handlowym.
Ale nie tylko. W Windy wierzymy, że sprawdzanie kamer internetowych na zewnątrz przed przygodą, na przykład przed lotem małym samolotem, może znacznie zwiększyć poziom bezpieczeństwa. —Ivo

Tropical Cyclone Ferdinand has strengthened and developed an eye, as confirmed in imagery from NASA-NOAA’s Suomi NPP satellite.
The Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard Suomi NPP provided a visible image of Ferdinand and showed that an eye opened as the storm continued to intensify. A thick band of powerful bands of thunderstorms circled the eye.
NASA-NOAA’s Suomi NPP satellite found that Tropical Cyclone Ferdinand has developed an eye as it continued to strengthen in the Southern Indian Ocean on Feb. 25, 2020.
On Feb. 25 at 10 a.m. EST (1500 UTC), the Joint Typhoon Warning Center of JTWC noted that Tropical cyclone Ferdinand was located near 15.8 degrees south latitude and 116.5 degrees east longitude, approximately, 413 nautical miles north-northeast of Learmonth, Western Australia.
Ferdinand was moving to the southwest and maximum sustained winds had increased to 90 knots (104 mph/167 kph). That is the equivalent of a Category 2 hurricane on the Saffir-Simpson hurricane wind scale.
JTWC forecasts that Ferdinand will move southwest and strengthen slightly more before starting to weaken. The storm is then expected to curve to the northwest through the Southern Indian Ocean.
Tropical cyclones are the most powerful weather event on Earth. NASA’s expertise in space and scientific exploration contributes to essential services provided to the American people by other federal agencies, such as hurricane weather forecasting.

The weather event known as the "Calima" came to Canary Islands again on Saturday afternoon. Strong winds blowing out of Western Sahara brought massive dust storm to northern Canaries, leading to cancelation of all flights in and out of Gran Canaria and all flights leaving Tenerife, due to severely impacted visibility.
Gran Canaria, Fuerteventura and Lanzarote are among the most affected locations. To see the extent of the storm, check out the webcams on Windy and the videos shared via Twitter (embeded below).
The storm is so huge it's visible from space as you can see in the satellite loop from 12 a.m. to 6 p.m. UTC today.
