A statistical analysis of vertical shear effect on tropical cyclone intensity change in the North Atlantic
[1] Based on the best track data of tropical cyclones (TCs) in the North Atlantic and the NCEP/NCAR reanalysis during 1981–2008,the effect of vertical wind shear (VWS) between different vertical levels and with different directions of shear on TC intensity change for TCs of different intensities, translational speeds, and latitudes were statistically analyzed. The results show that TC intensity...
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 کاملTropical Cyclone Intensity and Structure Changes in relation to Tropical Cyclone Outflow
The overarching objective of this project is to identify impacts to tropical cyclone structure and intensity throughout the tropical cyclone lifetime. A common factor is the impact of midand upperlevel environmental conditions that affects formation and intensification of a tropical cyclone. It is hypothesized that during the formation process, the environmental interaction has maximum impact o...
متن کاملTropical 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 کاملReexamination of Tropical Cyclone Wind–Pressure Relationships
Tropical cyclone wind–pressure relationships are reexamined using 15 yr of minimum sea level pressure estimates, numerical analysis fields, and best-track intensities. Minimum sea level pressure is estimated from aircraft reconnaissance or measured from dropwindsondes, and maximum wind speeds are interpolated from best-track maximum 1-min wind speed estimates. The aircraft data were collected p...
