AB: Water vapor in the tropical upper troposphere plays a pivotal role in Earth's atmosphere. Previous studies have showed that a positive water vapor feedback will increase surface warming. Thus, it is critical to understand how the sensitivity of water vapor is related to sea surface temperature. Using climate model simulations obtained from the Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment, we are able to investigate the relationships between the mean humidity in the tropical upper troposphere and the tropical sea surface temperature. Furthermore, the analysis that was used for the above mentioned climate models is compared to measurements made by the Atmospheric Infrared Sounder (AIRS) during the period of January 2003 to December 2004.
