Aslkahuna wrote:The Persian Gulf is a desert not because of the lack of moisture in the lower levels (they have the highest average Summer dewpoints in the World to go with the SSTs) but because of intense capping from subsidence and very warm air aloft from the Subtropical High. Yuma and SoCA Deserts from Needles south often see dewpoints in the high 70's and low 80's and they frequently get no rain from that moisture for the same reason. In order to see activity under those conditions one needs some source of dynamics to provide lift which in the case of Yuma is frequently a MCV or wave disturbance that has crossed Mexico from the GOM.

That is really unbearable.
