A Cold Front from 41,000 ft as compared to a Weather Map

Post by TTJJ »

In the spirit of “all knowledge is good knowledge”, I post this:

I was flying from Palm Springs California to Pittsburgh in October 2013 at 41,000ft, when I came across a situation that I thought might be useful for students and Instructors alike.

These pictures are of a Cold Front that crosses Kansas and extends down to Texas, as depicted on the accompanying weather map.

My position is the little aircraft symbol on the Navigation Display. The position of the aircraft does not completely jive with the weather map because I took a little time after I photographed the Navigation Display to take the picture of the actual front.

On the Navigation Display there are some green dots in front of the aircraft and a little to the left and right. That is the Front on the aircraft’s weather radar, extremely zoomed out. The radar returns match up with the weather map quite well.

We are traveling East. The pictures are out the left window looking North.

You may notice that the wind indicated on the weather map is 100 kts. The actual wind is in green in the top left corner of the Navigation Display. It is pretty close to the predicted value.

Any Instructor who wishes to may use these at will for non-commercial purposes.

It is sometimes hard to get a grasp of the overall situation when you are down in the middle of it all. I hope this helps someone.

That's really cool! I've never see a real picture of an entire cold front. Thanks for sharing!

It's cool how you can see the shadow of every cloud cast clearly on the ground.

So as a newb, I am basically seeing the cold front moving east, pushing the warmer air above it, and creating cumulus clouds as the air cools. Have I grasped the basics ? :D
