Trends in tropical circulation over the pacific during the last decade
The Aqua spacecraft decadal time span generated a vast volume of data that can be used for climate change studies. Here we use these data to investigate the tropical circulation response to global warming during the last decade. We use the Atmospheric Infrared Sounder (AIRS), Advance Microwave Sounding Unit (AMSU) and the Advanced Microwave Scanning Radiometer for EOS (AMSR-E) data obtained on Aqua spacecraft to determine the trends in the surface and mid-troposphere temperatures, as well as trends in cloudiness, Outgoing Longwave Radiation (OLR) and precipitation over the West and East Pacific in 2002-2011. The Aqua instruments deliver accurate, simultaneous measurements of the state of the atmosphere twice per day. We find that the tropical (Walker) circulation over Pacific Ocean has been accelerating during this last decade.
