The structure of Indian monsoon depressions is characterized by a vertical tilt to the west and south, a warm‐over‐cold temperature anomaly in the centre of the depression, peak horizontal winds at – hPa with cyclonic winds extending from the surface to the upper troposphere, and precipitation/cloud maxima in the west–southwest of   Symmetry is calculated by the storm-relative thickness perturbation in the –hPa layer across the storm, and the cyclone thermal structure is determined by the vertical profile of the height gradient (i.e., thermal wind) in the –hPa   Web view.

A case study of a typical explosive cyclone using hourly outputs from January shows that the explosive cyclone induces horizontal divergence within the surface‐mixed layer and upward flow that reaches m depths. The flow causes oceanic internal waves and temperature cooling because of the vertical advection in the deep :// The s: cyclone mesoscale structure Inconsistencies between the frontal structures observed in some cyclones and the Bjerknes () conceptual model led to refinements of the model and to the development of new conceptual models such as that proposed by Shapiro and Keyser ().

The Norwegian Cyclone model also includes a description of the vertical structure of the warm, cold and occluded fronts, and the precipitation and cloud development associated with these fronts (bottom portion of Fig.

), and Fig. illustrates the typical cloud types in various regions of the cyclone. This model, sometimes referred to as The future sustainability of our planet places the American Meteorological Society at the center of the grand chal­lenge of our times.

As a result, the relevance of the AMS has never been more compelling, with a number of fundamental and interdisciplinary scientific problems that must be :// The Holland vortex showed a better vertical structure of wind speed in the longitudinal height section at 24 hours of forecast for the November cyclone while the structure was better for the Rankine vortex for the remaining two cyclones.

However, both the NGM and RFE models, ini-tialized at and UTC 13 March, predicted a mesotrough at the end of the cyclone’s life cycle and failed to reproduce other frontal cyclogenesis ~dalin/zhang-radevag-frontcyc1-mpdf.This chapter studies two Tropical cyclone (TC) cases, Typhoon Dan () and Typhoon Ketsana (), and discusses their rates of formation and relationship with the mesoscale convective activities through examining the numerical simulations of the two cases.

Many TCs generate from a single mesoscale convective System (MCS) or multiple MCSs; the physical processes under these two patterns are   Bay of Bengal (BoB) is an affluent region for the mesoscale (eddies) and synoptic scale (cyclones) systems.

It occurs primarily through the seasonal variations, dynamical instabilities and equatorial wind forcing mechanisms. The individual or cumulative effect of these changes is vulnerable to the coastal and marine ecosystems. For example, tropical cyclone (TC) AILA experienced a warm
