This cross section is layed through the whole system, cutting
aproximately through the center of the low pressure. The right-hand side of
the cross-section shows very similar characteristics to the cross-section
E-F, because it is cut through the occlusion. The isentropes form typical Y
shape and the coldest cloud tops (orange line) are located in the region
with the cold-front character. The other part of the occlusion cloud band,
to the left of the cross-section, is characterized by a large unstable area,
with two minima of potential temperature. Very prominent feature in this cross-section is the tropopause, folded down to about 300 hPa in the region of the low (behind the cold front). |
