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...

The development of intense warm-core seclusion (Shapiro and Keyser 1990) extratropical storms can occur from several different precursor disturbances. These include tropical cyclones that have undergone extratropical transition, maritime extratropical cyclones with both coldcore baroclinic and shallow diabatically generated warm core backgrounds (Moore and Montgomery 2004), and polar lows. With...

The formulation and testing of an enhanced Statistical Hurricane Intensity Prediction Scheme (SHIPS) using new predictors derived from passive microwave imagery is presented. Passive microwave imagery is acquired for tropical cyclones in the Atlantic and eastern North Pacific basins between 1995 and 2003. Predictors relating to the inner-core (within 100 km of center) precipitation and convecti...

The CloudSat 94-GHz Cloud Profiling Radar was designed to provide global information on the vertical structure of clouds. It was launched in April 2006, joining the A-Train of earth science satellites. Although primarily focused on clouds and climate, the CloudSat radar also provides a unique view of the vertical structure of clouds in tropical cyclones. The authors use data from CloudSat and o...

By using a half soap bubble heated from below, we obtain large isolated single vortices whose properties as well as their intensity are measured under different conditions. By studying the effects of rotation of the bubble on the vortex properties, we found that rotation favors vortices near the pole. Rotation also inhibits long life time vortices. The velocity and vorticity profiles of the vor...

Based on the availability of hemispheric gridded data sets from observations, analysis and global climate models, objective cyclone identification methods were developed and applied to these data sets. Due to the large amount of investigation methods combined with the variety of different datasets, a multitude of results exist, not only for the recent climate period but also for the next centur...

Bangladesh, with a population of 151 million people, is a country that is particularly prone to natural disasters: 26% of the population are affected by cyclones and 70% live in flood-prone regions. Mortality and morbidity from these events have fallen substantially in the past 50 years, partly because of improvements in disaster management. Thousands of cyclone shelters have been built and gov...

The winters of the 1980s were among the warmest on record over nonhem Siberia. Daily and monthly sea level pressures, 500 mb heights, and an index of Atlantic storm track extent (toward the northeast) and intensity, are used to examine atmospheric circulation variability during extremely warm and cold winter months in Siberia. In recent years, the comparatively warm months are associated with a...

In the first part of this chapter, we give a review of the relationship of climate and tropical cyclones on various time scales, from intra-seasonal to decadal. The response of tropical cyclone activity to natural modes of variability, such as El Niño-Southern Oscillation and the Madden Julian Oscillation in various regions of the world are discussed. Genesis location, track types and intensity...

Super typhoons (STYs), intense tropical cyclones of the western North Pacific, rank among the most destructive natural hazards globally. The violent winds of these storms induce deep mixing of the upper ocean, resulting in strong sea surface cooling and making STYs highly sensitive to ocean density stratification. Although a few studies examined the potential impacts of changes in ocean thermal...
