Abstract

This paper reports the observation of persistently low tropopause temperatures (100hPa temperatures, T-100) and ozone at 100hPa throughout the year as compared to the corresponding zonal mean values over the Bay of Bengal (BOB) region. The long term mean T-100 (i.e., from January 2006-December 2009) over the BOB is similar to 2.2K lower than the zonal mean values over this region. The multiple linear regression analysis has been carried out to study the role of convection and ozone in giving rise to the persistently low T-100 over the BOB. Results show that the low ozone mixing ratios contributes similar to 1.2K and convection contributes similar to 0.35K to the persistently low T-100. The contribution of convection to the persistent low T-100 is mainly during the boreal monsoon season.
