The continental You is situated in the changeover region anywhere between expected drying in the subtropics and you may estimated wetting on mid- and you will higherlatitudes. You will find some differences in the region regarding the change anywhere between CMIP3 and you may CMIP5 patterns, meaning that around remains uncertainty from the real located area of the change area.
