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 کاملThe Role of Tropical Cyclones in the Formation of Tropical Upper-Tropospheric Troughs
Tropical upper-tropospheric troughs (TUTTs), also known as midoceanic troughs, are elongated troughs that appear in summer monthly averaged maps of the upper-tropospheric flow over the oceans. The transient part of these climatological features is composed of TUTT cells and their origin is the subject of this study. TUTT cells often occur to the east of tropical cyclones. A nonlinear shallow wa...
متن کاملHelical organization of tropical cyclones
In this work we consider a helical flow organization on small and large space scales in a forming tropical cyclone and offer a quantitative analysis for early stages in evolution of large-scale helical vortex based on diagnosis of a set of integral helical and energetic characteristics. Using the data from a near cloud-resolving numerical simulation by Regional Atmospheric Modeling System (RAMS...
