• Is there an option to show local time instead of Z in the weather station slider?

    I understand this is a standard in aviation, marine, and military applications, but for us regular folks seeing local time without having to do math would be much more useful. I'm hoping there is a setting that I missed somewhere, or that one can perhaps be added?

  • Why is there a discrepancy between freezing altitude and air temperature?

    I'm looking at areas of the map where the temperature is -20°C or even lower, yet the freezing altitude iso line passing through same area shows 1400, which I assume is altitude in meters? Is freezing altitude different from freezing level? What am I missing?

    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 ;-)

  • On this day: Hurricane Camille made landfall in Mississippi on August 17, 1969

    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).

    Quick Facts

    • Hurricane Camille made landfall, along the Mississippi Gulf Coast near Waveland late in the evening on August 17
    • Camille is one of only four Category 5 hurricanes ever to make landfall in the continental United States (Atlantic Basin)
    • Camille ranks as the 2nd most intense hurricane to strike the continental US, and resulted in 256 deaths
    • The actual maximum sustained winds of the hurricane are not known as Hurricane Camille destroyed all the wind-recording instruments in the landfall area
    • Re-analysis data found landfall intensity and peak winds of 150 knots (roughly 175 mph) along the coast, with 900 mb pressure
    • A devastating storm tide of 24.6 feet occurred west of our area in Pass Christian, Mississippi.

    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.

  • After Canary Islands travel chaos. Copernicus tracks path of dust plume to Western Europe

    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.

  • Windy Tutorial: What is the difference between the reference time and the update time

    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.

    1. Reference time

    Reference time is the time when a model starts a new forecast block. The process consists of the following:

    • Initialisation - data are entered into the model, this creates Initial conditions (initialisation time) and then model starts calculating conditions.
    • Assimilation - normalisation on data and assembling data for computation.
    • Computation - calculating the future atmospheric rates of change in time increments.
    • Data extraction - extracting data into regular forecast intervals.
    • Data storage - data are stored and written in accessible format.
    • Data postprocessing - special postprocessing routines

    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.

    2. Update time

    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.

    When and how often are the weather data updated?

    The table below describes when and how often are the weather models updated. All times are in UTC.

    Where to find the reference and the update time

    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.
