I’m studying meteorology for PPL and after learning the big differences between cyclones and anticyclones, I came across a question that flipped all my knowledge on its head:
What pressure pattern may result from cold-air inflow in high tropospheric layers?
A: Formation of a low in the upper troposphere
I’ve spent hours on all facets of this question and I still don’t understand how cold air inflow can create a low in the upper tropospheric layers.
Apparently this cold air inflow at high tropospheric layers triggers a through, which would be a catalyst for ts and cb.
But at the same time it doesn’t make it clear how cold air can create a low, cyclone, which is actually characterized by rising warm air that cools.
There is a variation of this q that talks about
what weather conditions should be expected in an upper level through and it suggests that‘s
development of showers and thunderstorms.
But I thought throughs in lows happen at ground level, because air rises in lows.
