    • RE: Windy launches Satellite layer

      It's really really awesome!
      Thank you Ivo and Windy Team for your hard work! You made a unique brand new extremely useful feature again! Congrats!
      I think this satellite feature was waited by a huge amount of people, and now it became reality! From now everybody can use this eye-catching satellite feature and take care of their safety.
      My question is the same as @Gkikas-LGPZ about the INFRA+ feature colour overlay.

    • Ozone Layer and Ozone Hole - In general

      photo: helpsavenature.com;link: https://helpsavenature.com/ozone-layer-depletion-effects-causes;desc: Earth's atmosphere, Ozone layer and its position.;

      The ozone layer is the part of the Earth's atmosphere that has the most ozone in it.
      It's the atmospheric layer within the stratosphere, extending from a height of c. 20 to c. 30 km (c. 12 to c. 18 mi). The ozone layer protects living things from the harmful radiation of the sun. It absorbs dangerous ultraviolet radiation from the sun and serves to maintain the temperature of the atmosphere.

      photo: theozonehole.com;link: http://www.theozonehole.com/dobsonunit.htm;desc: Dobson unit.;

      A dobson unit is the most basic measure used in ozone research. One Dobson Unit (DU) is defined to be 0.01 mm thickness at STP (standard temperature and pressure). Ozone layer thickness is expressed in terms of Dobson Units, which measure what its physical thickness would be if compressed in the Earth's atmosphere. In those terms, it's very thin indeed. A normal range is 300 to 500 Dobson Units (3-5 mm), which translates to an eighth of an inch-basically two stacked pennies.

      photo: theozonehole.com;link: http://www.theozonehole.com/dobsonunit.htm;desc: Average ozone thickness.;

      In space, it's best not to envision the ozone layer as a distinct, measurable band. Instead, think of it in terms of parts per million concentrations in the stratosphere (the layer six to 30 miles above the Earth's surface).

      The unit is named after Gordon Dobson, one of the first scientists to investigate atmospheric ozone.
      photo: theozonehole.com;link: http://www.theozonehole.com/dobsonunit.htm;desc: Gordon Dobson.;

      NASA uses a baseline value of 220 DU for ozone. This was chosen as the starting point for observations of the Antarctic ozone hole, since values of less than 220 Dobson units were not found before 1979. Also, from direct measurements over Antarctica, a column ozone level of less than 220 Dobson units is a result of the ozone loss from chlorine and bromine compounds.

      photo: en.wikipedia.org;link: https://en.wikipedia.org/wiki/Ozone_depletion;desc: Ozone hole over Antarctica.;

      Ozone depletion describes two related events observed since the late 1970s: a steady lowering of about four percent in the total amount of ozone in Earth's atmosphere (the ozone layer), and a much larger springtime decrease in stratospheric ozone around Earth's polar regions. The latter phenomenon is referred to as the ozone hole. There are also springtime polar tropospheric ozone depletion events in addition to these stratospheric events.

      The main cause of ozone depletion and the ozone hole is manufactured chemicals, especially manufactured halocarbon refrigerants, solvents, propellants and foam-blowing agents (chlorofluorocarbons (CFCs), HCFCs, halons), referred to as ozone-depleting substances (ODS). These compounds are transported into the stratosphere by wind after being emitted from the surface, mixing much faster than the molecules can settle. Once in the stratosphere, they release halogen atoms through photodissociation, which catalyze the breakdown of ozone (O3) into oxygen (O2). Both types of ozone depletion were observed to increase as emissions of halocarbons increased.

      Ozone depletion and the ozone hole have generated worldwide concern over increased cancer risks and other negative effects. The ozone layer prevents most harmful UVB wavelengths of ultraviolet light (UV light) from passing through the Earth's atmosphere. These wavelengths cause skin cancer, sunburn and cataracts, which were projected to increase dramatically as a result of thinning ozone, as well as harming plants and animals. These concerns led to the adoption of the Montreal Protocol in 1987, which bans the production of CFCs, halons and other ozone-depleting chemicals.

    • RE: Wind accumulation let you track the hurricanes

      It's a really good feature, and a very nice imrovement of Windy!

      And from now it's much easier to locate tropical storms with the 'Active hurricanes' feature. We can locate easily the wanted one by clicking on its name, and it jumps into it. In addition we can see here the category types and the punctual positions of each Hurricane.

      Here we can see the "Active hurricanes" option in the Menu:

      Screenshot-2018-09-25-21.52.00.png

      In this example picture we can see the Trami Thyphoon and its properties:

      Screenshot-2018-09-25-21.42.23.png

      Thank you very much guys, for your persistent hard work! This website is amazingly beautiful with a lot of features, plus it saves lives... So it has all the features that an excellent weather page needs to have.

    • RE: Which model should Windy implement next? Please vote.

      @ivo
      Vote number 2: AROME

      Windy has no such a good resolution model yet as AROME working on, so it could be very interesting, especially for mountainous areas to compare any other model's data to the new AROME model with (approx) 2 km resolution.
      So my special vote is for AROME, because it's more interesting for me than the other models.

    • RE: how do I know the type of clouds in a certain region?

      @deltaromeo
      You can choose from several cloud layers: low/medium/high clouds, cloud base and cloud tops, or if you choose the main "Clouds" layer you will get a complex view of the clouds with the significant weather, such as rain.

      You can see only the cloud coverage in percentage given.
      I know that it's not the same that we use in aviation, where the cloud coverage is reported by the number of "oktas" (eights) of the sky that is occupied by cloud. But it's easy to compare the percentage of the coverage to how many oktas it can be.

      The indication has 4 stages:

      • FEW (few, meaning 1-2 oktas),
      • SCT (scattered, meaning 3-4 oktas)
      • BKN (broken, meaning 5-7 oktas)
      • OVC (overcast, meaning 8/8 oktas, full coverage)

      For example:
      SCT050 - means that the scattered cloud has a cloudbase of 5000 ft.
      BKN100 - means that the broken cloud has a cloudbase of 10000 ft.

      Anyway you can activate the "Airports" overlay on the bottom of the right hand side of the website page (the airplane icon next to the "forecasted weather" cloud icon), so with this option you can see the airports (small circle signs, their colours are depends on the weather related flight rules (green - VFR, blue - MVFR, red - IFR, pink - LIFR) or if the airports hasn't have weather report services, their colours are gray), and of course their weather reports (METARs, TAFs) - in which you can read the actual and previous reports, Runways infos, Webcams and NOTAMs (big advantage is you can switch in the METAR and NOTAM menus from "raw mode" to decrypted view, so it helps you to understand what it means, plus in the NOTAM menu you are able to make each NOTAM report that you want to put into "read status", so it puts a check mark to that).

      Some other useful abbreviations in aviation:
      SKC - Sky Clear
      NSC - No (nil) Significant Cloud
      CB - Cumulonimbus (big, intensive cloud type through several athmosphere layers to high altitude, this is the most dangerous type of cloud with heavy rain, ice conditions and turbulence)
      CU - Cumulus (generally low level puffy clouds, they can produce little or no precipitation, they can grow into the precipitation-bearing congestus or cumulonimbus clouds)
      TCU - Towering Cumulus (significant, intense clouds with strong updrafts, turbulence and possibility of rain)
      CAVOK - Ceiling and Visibility OK (a weather status report for pilots, when visibility is at least 10 km, there are no clouds below 5000 ft or minimum sector altitude (whichever is higher), and there is no current or forecasted significant weather such as precipitation.

    • RE: Madeira island radar.

      @ecavaleiro
      I asked exactly the same recently from @dzuremar and he said it's because of the source decreased its range due to some reason. For Madeira they not get the official data, but they get it from Rainviewer.com. Anyway as you can see recently there are a lot of newly added radar coverages, these big and fast extensions are thanks to Rainviewer (such as: Portugal, Turkey, W part of Russia, Australia).

    • RE: Forest fire

      @EMX325

      This feature CAME TRUE and works fine now on Weather Warnings layer.
      In addition it includes several other warnings, not only forest fire, but because of this, from now Windy has much more useful and life saving capabilities with this brand new "Weather Warnings" layer than ever.

      The weather warning types:
      • Rain
      • Thunderstorms
      • Flood
      • Fire
      • High temperature
      • Low temperature
      • Wind
      • Fog
      • Waves, sea phenomenon
      • Snow
      • Air quality
      • Avalanches

      There are 2 colour scheme options for the layer:
      • colorize by the intensity of the phenomenons (moderate, severe, extreme)
      • colorize by the type of danger (according to the list above)

      The signs of different phenomenas discretely signed by little symbols as you can see on the screenshots below, it has a description for its meanings on the bottom right corner in the second choosable colour scheme (as you can see on the second screeshot below).

      And finally, it has a time changing option to show the corresponding data on the map, which are the followings:
      • All available
      • Today
      • Tomorrow
      • Later

      Example screenshots:

      • colorize by the intensity of the phenomenas scheme option

    • RE: Cloud Base Information

      @takumhara
      Windy changed it from cloud base to ceiling, but it is running under the same name on Windy. So the ceiling means > 50% of sky covered by clouds, in aviation it is higher than 4 octas, so it can be BKN = Broken or OVC = Overcast, where BKN = 5-7 octas, OVC = 8/8 octas fully covered.

      And to answer your qestion, this parameter gives the height of ceiling in meters (m) or feet (ft) above the level of the model (ECMWF) orography, so it is AGL.

      Read the corresponding article of Ceiling:
      https://confluence.ecmwf.int//display/FCST/43r1+new+parameters%3A+Ceiling

      But be aware of it, because of the ECMWF model has a 9km resolution, so it's sampling the terrain with 9 km steps. If you are planning around mountainous areas, you can't rely on it, do not use it for planning in such areas.

    • RE: Windy launches "Observation vs. Forecast"

      @jsdhornby
      That coloured area represents the observed temperature on the upper side and the dew point on the lower side measured by the weather station. And its colour is corresponding to its colour scale depending on its value.

      You can note that the more closer these two lines (values) to each other, the more saturated is the air. Obviously when the two values are equal --> the air is 100% saturated in this case (it's depicted on windy as a very little gap between the two lines, but above the chart at the value indicator you can read 2 equal values). In this 100% saturated air, the air contains a lot of moisture and there exist a low visibility condition, due to the very high probability of fog creation, which can transform into a low level stratus cloud with the help of a little wind. So it can influences the developing weather phenomenas.

      Anyway, the other 2 dashed lines represents the forecasted TEMP and DEW POINT, for that weather model, which you select at the bottom of the chart.
      Screenshot-2019-02-14-21.05.58.png

      Or if you are thought about the starting pop up charts and not the weather stations' "observation vs forecast" charts, there the coloured area represents only the forecasted temperature, as you can see it below.
