Re: Why do troughs overpower hurricanes?

A very weird thought I just had is to think of the North Pole as the center of a permanent huge cold core storm with eyewalls going all the way around the Earth. One eyewall may be outlined by the jet stream.

So much for keeping things simple....


I noticed this pic on how the transition height from where the tropopause and the stratosphere can depend on the latitude of the storm.

Maybe this will be demonstrated in the 'AMSU Radial/Height Cross Sections' pics for each cyclone.

Figure 3. An alternative model of frontal-cyclone evolution (Shapiro and Keyser, 1990): incipient broad-baro-clinic phase (I), frontal fracture (II), bent back front and frontal T-bone (III), and warm core frontal seclusion (IV). Upper: sea level pressure (solid), fronts (bold), Figure and cloud signature (shaded). Lower: temperature (solid), and cold and warm air currents (solid and dashed arrows).
