Intensified Arabian Sea tropical storms
Tropical cyclones over the Arabian Sea in the pre-monsoon season (May–June) have intensified since 1997 (ref. 1, Fig. 1a) owing to significant reductions in storm-ambient vertical wind shear (VWS) in the troposphere; these reductions have decreased on average by about 3m s from the pre-1997 epoch (1979–1997) to the recent epoch (1998–2010). The authors attribute the reduction of premonsoon VWS ...
متن کاملCirrus Canopies in Tropical Storms
An analysis is made of the generation, advection, and dissipation processes of the cirrus canopy in tropical storms with particular emphasis on the formation of sharp edges. Although subsidence and accompanying evaporation may be factors, this formation is closely tied with the wind flow pattern near the edges. The stronger the radial wind velocity in the vicinity of the edges, the greater is t...
متن کاملTitan’s Tropical Storms in an Evolving Atmosphere
The Huygens probe landed in a damp lake bed fed by fluvial channels, indicative of past rainfall. Such washes, interspersed with vast dunes, are typical of Titan’s tropical landscape. Yet, Cassini-Huygens measurements reveal a highly stable tropical atmosphere devoid of deep convective storms, and the formation of washes in dune fields is not understood. Here we examine the effects of seasonal ...
متن کاملGlobal View of the Origin of Tropical Disturbances and Storms
A global observational study of atmospheric conditions associated with tropical disturbance and storm development is presented. This study primarily uses upper air observations which have become available over the tropical oceans in the last decade. Climatological values of vertical stability, low level wind, tropospheric vertical wind shear and other parameters relative to the location and sea...
متن کاملFormation of tropical storms in an atmospheric general circulation model
The formation of tropical storms in a low-resolution Atmospheric General Circulation model is studied over the western North Pacific region during the June–October season. The model simulates the mean annual cycle of storm number in this basin quite well. Time-dependent composites of the storms are formed and analyzed, with a focus on the temporal evolution of quantities averaged in space aroun...
