E. Dessler adessler@tamu.edu Dept. of Atmospheric Sciences, Texas A&M University, TAMU 3150, College Station, TX 77843-3150, USA Halogen Occultation Experiment measurements of H<sub>2</sub>O are used to investigate the influence of mid-latitude convection on the summertime overworld between 30&deg; N and 40&deg; N. We find that most of the convective influence over this latitude range occurs over the Asian monsoon and over North America. Over North America, the effects of convection extend to ~410 K (17.5 km). Over Asia, the effects of convection extend to ~460 K (19 km), about 50 K (1.5 km) higher than over North America.
