Climatology of Cyclones, Anticyclones and Storm Tracks: Revision of Concepts

This paper has the finality of describe climatology of extratropical cyclones, anticyclones and storm tracks for the NH and SH. There is a long history of studies on the characteristics of synoptic systems, beginning with classical work on mid-latitude cyclones. For the SH, analyses of pressure data provide extensive statistics of the climatology of synoptic systems. Interestingly, the anticycl...

postnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)

1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...

Workshop on Tropical Cyclones and Climate

In final form 31 October 2006 ©2007 American Meteorological Society ropical cyclones (TCs) are among the most destructive of natural disasters. The statistics of TC occurrence and intensity are influenced by variations in the large-scale climate, but many aspects of this influence are poorly understood. Even less is known about the influence of tropical cyclones on the large-scale climate. Thes...

Tropical Dust Cyclones on Mars

Introduction: Atmospheric dust plays an important role in regulating the climate of Mars and strongly influences the deposition of incoming solar energy and outgoing infrared radiation, thereby affecting atmospheric dynamics through heating. The lifting of dust from the surface is fundamentally a result of atmospheric circulations, and this provides an opportuntity for feedback between atmosphe...
