Clouds in Tropical Cyclones
Clouds within the inner regions of tropical cyclones are unlike those anywhere else in the atmosphere. Convective clouds contributing to cyclogenesis have rotational and deep intense updrafts but tend to have relatively weak downdrafts. Within the eyes of mature tropical cyclones, stratus clouds top a boundary layer capped by subsidence. An outward-sloping eyewall cloud is controlled by adjustm...
متن کاملThe Dynamics of Tropical Cyclones
The specific objectives of the current effort are: 1. To continue our study of the dynamical processes in tropical cyclones responsible for looping or erratic motion; 2. To continue the development of methods for (a) the introduction of synthetic tropical-cyclone-scale vortices in operational forecast models and (b) ensemble forecasting of tropical cyclones; 3. To continue a sensitivity study o...
متن کاملTargeted Observation of Tropical Cyclones
The advance in targeted observations of tropical cyclone movement is reviewed in this article. The targeted observations from DOTSTAR (Dropwindsonde Observations for Typhoon Surveillance near the Taiwan Region) in understanding and improving the tropical cyclone track predictability is highlighted, along with the progress of the field program of THORPEX-PARC in the summer of 2008. The impact of...
متن کاملMesoscale Processes in Tropical Cyclones
I have four long-term goals. My first goal is to finalize the large body of work already carried out by the PI on the predictability of tropical cyclone (TC) forecast tracks out to 72 hours ahead. My second goal is to apply similar, as well as new, ideas to the predictability of forecast intensity out to 72 hours ahead. My third goal is to carry out observing system simulation experiments (OSSE...
متن کاملOvershooting convection in tropical cyclones
[1] Using infrared satellite imagery, best-track data, and reanalysis data, tropical cyclones are shown to contain a disproportionate amount of the deepest convection in the tropics. Although tropical cyclones account for only 7% of the deep convection in the tropics, they account for about 15% of the deep convection with cloud-top temperatures below the monthly averaged tropopause temperature ...
