Tropical sea surface temperature, vertical wind shear, and hurricane development
[1] The anomalously strong hurricane activity in the Atlantic sector during the recent years led to a controversy about the impact of global warming on hurricane activity in the Atlantic sector. Here we show that the temperature difference between the tropical North Atlantic and the tropical Indian and Pacific Oceans (IndoPacific) is a key parameter in controlling the vertical wind shear over t...
متن کاملMicrowave radiometer observations of interannual water vapor variability and vertical structure over a tropical station
The intraseasonal and interannual characteristics and the vertical distribution of atmospheric water vapor from the tropical coastal station Thiruvananthapuram (TVM) located in the southwestern region of the Indian Peninsula are examined from continuous multiyear, multifrequency microwave radiometer profiler (MRP) measurements. The accuracy of MRP for precipitable water vapor (PWV) estimation, ...
متن کاملHigh-level Warmings Over a Tropical Station
Examination of the available rocketsonde data for the tropical station, Thumba, India, has shown that warmings, less pronounced than in the case of middleand high-latitude stations but of noticeable magnitude, and coolings of similar magnitude occurred in the mesopheric and upper stratospheric levels during the period, December 1970-htarch 1971. This was the only winter period when observations...
متن کاملEffects of Vertical Wind Shear and Storm Motion on Tropical Cyclone Rainfall Asymmetries Deduced from TRMM
Vertical wind shear and storm motion are two of the most important factors contributing to rainfall asymmetries in tropical cyclones (TCs). Global TC rainfall structure, in terms of azimuthal distribution and asymmetries relative to storm motion, has been previously described using the Tropical Rainfall Measuring Mission Microwave Imager rainfall estimates. The mean TC rainfall distribution and...
متن کاملShear-forced vertical circulations in tropical cyclones
[1] The forced secondary circulation (FSC) by the vertical shear of horizontal winds is isolated from the latent heating and friction FSCs associated with a model-simulated hurricane vortex. This is achieved by use of a newly developed potential vorticity inversion and quasi-balanced vertical motion equations system. Results show that latent heating forces intense updrafts in the eyewall and sl...
