Icing Airmet Maps

[coloradobluesky]

Anyone know of any good icing airmet maps? I can't seem to find them.

Also, any maps of tops?

I use this for icing http://aviationweather.gov/icing

You might try aviationweather.gov for AIRMETs.

Got it. Thanks Ron.

Some of ScottD's free videos might be useful.

Here is two I use in addition to the ones mentioned above...

And for tops, I like this one. Anything salmon or orange is good for me when there is not a lot of convection. I fly vfr over the top safely using this, satellite/radar imagery, ceilings and sky coverage.

I like this one for snow depths. Can you believe it already shows some up in the NW!

Millibars for altitude? I don't get it. So it says 900 milibars for cloud top pressure. So what are the tops in feet?

Level.....Standard Height
1000 MB......364 ft......111 m
925 MB......2498 ft......762 m
850 MB......4781 ft.....1458 m
700 MB......9882 ft.....3013 m
500 MB.....18289 ft.....5576 m
400 MB.....23574 ft.....7187 m
300 MB.....30065 ft.....9166 m
250 MB.....33999 ft....10366 m
200 MB.....38662 ft....11787 m

The "standard" millibar levels are approximately:

1000 = sea level
850 = 5000 feet
700 = 10000 feet
500 = 18000 feet
400 = 24000 feet
300 = 30000 feet
250 = 34000 feet
200 = 39000 feet

You'll notice a correlation between those values and the winds aloft ("constant pressure") chart heights. So, 900mb would be about 3500 feet.

I printed the above chart and have it taped to my computer. Very good reference if you really like studying wx.

Why is the no cloud tops product on the aviationweather.gov site? Seems like it would be pretty useful.

Can't this be obtained from the Skew-T?

I like this presentation...lots of data on one page displayed over time...

Yes. I am thinking I would have to look at several points along my route, but have not used it for that. I guess I also like a big horizontal, colorful shot of the atmosphere vs a vertical section. It always seems very accurate for me with stratiform clouds. If convective clouds exist, I am staying underneath or on the ground.

I keep thinking ScottD recently did a video about how to use two or three of the weather products to get answers like this. But I'm having not much luck finding it on my own. I need to email him the general questions from this thread. I'll share his answer.
