RE: how do I know the type of clouds in a certain region?
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)
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: July Snow Off Florida Coast???
First of all remember that it's free.. so such a little problem is not so significant problem.
Despite of this little thing it's still work fine, and still the best weather visualisation website on the internet in my opinion!
It's okay, that there ought to be a workaround. But if this is an error of the weather models, Windy has nothing to do with it, because this website is only capable to visualize the weather models' datas. But I don't know whether is it a programming error at windy, or what. Because according to my previous reply, as the screenshot of the Meteogram shows that there is no snow at all.
So it would be great, if anybody expert programmer could look at this labeling error, maybe it can be simply fixed.
You can activate the tide forecasts at the right hand bottom of the website page (the last icon on the icon bar, next to the webcam icon).
By activate it, you will experience that it will appears at some coastlines, unfortunately there are no tide indication data for all the shores.
You can find tide forecasts in North-West of Europe, in the USA coatlines up to Canada, in Central America (such as Mexico, The Bahamas, Cuba, Dominican Republic, Guatemala, Nicaragua), in the East Coast of South America, in Japan, in Australia, in Papua New Guinea, in Solomon Islands, in New Zealand and some other little islands.
Some examples by screenshots:
(the little yellow points at coastlines indicates the tide forecasts)
RE: July Snow Off Florida Coast???
I still think the same, with the NAM 5km model too.. maybe it's a common error of both the two weather model. I live in Europe, but I don't think that snow condition in Florida or near to that can be true in July....
I think that is only rain, despite of that the flag indicator shows "snow". Or if somehow it could snowing in some altitude, thats anyway melts in lower altitude, and change its consistency, so it becomes rain at all.
In addition, if you look at the Basic, or the more detailed Metogram forecasts interface, you will see that it doesn't mension any snow, but the flag indicator says: "Rain, snow", so it proves that it's false indication.
The screenshot of this:
It shows only heavy rain (29 mm).
RE: July Snow Off Florida Coast???
Might want to take a look at the new rain/thunderstorms feature; shows snow off Florida in the Gulf.
It's maybe a little error of the weather model (ECMWF), because of its appears only at some little points, it's hard to find anyway, at least for me it was hard to find that "Rain, snow" or "Wet snow" flagged little area.. The reason that I think this is an error is come from that I watched several other layers: such as Rain accumulation, New snow, Thunderstorms, Temperature (surface and 1500m), Clouds and CAPE index. I attach the screenshots of all the layers that I compared and from which I made the conclusion.
Here you can see that it came westwards in the last few hours (according to your screenshot), and the little "snowy" error area still there.
And I have found these two other indications (snow, rain with snow) near the above point, but these are hard to find too.. the indicator shows it only at little specific points.
This screenshot shows the rain accumulation data for the same area.
As you can see, the unique snow layer doesn't show anything.
The thunderstorm layer shows that close to this "snowy" point there is a light thunderstorm, and these "error snowy points" can be found at the edge of that.
The temperature layer shows that there is 26°C at the surface right now and 17°C at 1500m height. So these are not really match the conditions for the formation of snow..
The clouds layer shows that there is overcast clouds (99%) and it shows for this point a 1,1 mm rain.
And at the last screenshot you can see the CAPE index layer, which indicate a light thunderstorm too, according to the amount of energy.
So according to the above threads, I think this is an error of the weather model - ECMWF.
And the "snow" indication is a false signal in this case.
I hope that I can help you with this.
RE: how do i interpret thunderstorm layer?
As my knowledge and experience, you can reach the thunderstorm layer by choose the "Rain, thunder" layer option, and beside this you can choose the unique "Thunderstorms" layer to see only the thunderstorm layer. If you choose the "Rain, thunder" uniform layer you will see a complex layer on the map, including: rain, snow and thunderstorm layers at once, which is nice to see in my opinion. The thunderstorm layer appears as little lightning signs, and the storm intensity is distinguishable by its size and luster. So in the case of light thunderstorm, it's small in size and appears as pale, transparent lightning signs; but in the case of strong severe thunderstorm, it becomes bigger in size and appears as shiny, luminous lightning signs.
I have found a severe thunderstorm in India, I made screenshots of both the two cases that I wrote: the complex layer "Rain, thunder" and the unique "Thunderstorms" layers.
I attach these screenshots here:
RE: About Windy
What does height mean? Above sea level? My height is 157ft
The "Height" word stands for the height above ground/terrain.
The "Altitude" word stands for the height above mean sea level (MSL).
"Elevation" word stands for (in aviation mainly) the height of an airport or station above MSL.
"Flight Level - FL" word stands for (in aviation) the vertical altitude at standard pressure, nominally expressed in hundreds of feet. The standard pressure can be found in the ISA - International Standard Athmosphere conditions. This pressure is 1013,25 hPa or 29,92 inHg. An example: FL300 means 30.000 feet, it have to include always 3 characters, so in case of 9000 feet, it will be FL090.
Anyway the pressure is decreasing with increasing altitude, so do the air density.
Pilots must change their altimeter setting during the climb session from QNH (athmospheric pressure adjusted to mean sea level) to standard (1013,25 hPa or 29,92 inHg) at a given altitude, the so called "Transition Altitude", and backwards during the descent session they have to change the altimeter setting back to local QNH at an altitude so called "Transition Level".
RE: Change from kilometers to miles
As I see, there is no answer yet. Though I'm an iPhone owner, but I hope I can help you.
There is no option for this on iPhone as I know, maybe nor on android.. You can change it only on the online https://www.windy.com/?visibility,46.920,21.533,4 website (at visibility) by clicking to the unit in used, so it will switch to another units, you can choose that you want by your discretion.
Anyway you can determine it by calculator with the following formulas:
1 KM = 0,54 NM (nautical miles)
1 KM = 0,62 SM (statue mile)
1 NM = 1,852 KM
1 SM = 1,61 KM
Or direct change it simple with a converter application, such as "Vert" or "Amount Plus", these are the best converters as my experience.
You have 3 options with the units of visibility on the website:
- flight rules (LIFR, IFR, MVFR, VFR - in aviation)
