Winds Aloft

DaleWP1

Precursor: I did search for this and see other posts that are similar, but I can't get the threads to display.

I see how to change the altitude with the slider, but I don't understand how to read the changes. The timeline at the bottom displays, but the values don't change with the slider change. I don't understand what the other acronyms mean either (METROBLUE, NAM, etc...). Would one of you help me understand how to read the winds aloft?

Thanks!

When you adjust the Altitude slider at a given level, the wind map shows the wind at this level, and using the timeline slider you see the wind forecast changing on the map.
Then you probably talk about the Meteogram below the time slider. It shows only forecast data at ground level. If you choose Airgram you get wind, temperature and clouds at different level.

METEOBLUE and NAM are weather models in addition of ECMWF and GFS

Thanks, idefix37.

I was able to get to the same place as in your pic. When I select the Airgram view, then move the slider on the right to change the altitude, nothing changes in the Airgram view. So I guess I need a little more explanation (I swear, I'm not normally this dense -- just new to the weather-world). So are the winds at different altitudes separated by the dotted lines in the colorful area? If so, how do you know what those individual altitudes are?

I did figure out that, for my area, I need to use the NAM model. So Now I just need to know if I'm on the right track with with winds.

Thanks again, for the help!

The altitudes are shown by the dotted lines. They correspond to the figures in light grey in the left side of the diagram.

So you see from the bottom 1000h, 950h, 900h, 850h....That means 1000 hPa, 950hPa, 900hPa, 850hPa... They are the mean pressure levels according to the altitude. You can get the corresponding altitude to these pressure levels on the altitude slider where the altitude is expressed in ft, m, and hPa.
