Abstract: A possible mechanism for the diurnal oscillations of tropical cyclones is presented. In the conceptual model developed to explain these features, the diurnal cycle of net radiation at the cloud tops is identified as the ...

Abstract: The effects of 10 climatological and persistence variables (latitude, maximum wind speed, 12-h change of maximum wind speed, longitude, distance to land, Julian date, sea surface temperature, speed of movement, zonal ...

Abstract: The maximum potential intensity (MPI) of a tropical cyclone represents a theoretical upper limit to the strength of the storm imposed by the laws of physics and the energy available to the system in the atmosphere and the ...

Abstract: The log of the first voyage of Christopher Columbus to the New World provides valuable information on the meteorological conditions of September 1492. Comparison and analysis of the descriptive accounts of weather made by ...

Abstract: A new dataset of tropical cloud clusters, which formed or propagated over the Atlantic basin during the 1998?2000 hurricane seasons, is used to develop a probabilistic prediction system for tropical cyclogenesis (TCG). ...

Abstract: An alternative 24-h statistical hurricane intensity model is presented and verified for 13 hurricanes during the 2004?05 seasons. The model uses a new method involving a discriminant function analysis (DFA) to select from ...

Abstract: In recent years a number of different methods have been proposed for the inclusion of the effects of cumuli in numerical models of tropical cyclones. In this paper several of the Kuo-type parameterizations have been tested ...

Abstract: The primary objective of this research is the development of a statistical model that will provide tropical cyclone (TC) intensity guidance for the eastern North Pacific (ENP) superior to that provided by climatology and ...

Abstract: ropical cyclones with nontropical characteristics are being identified more frequently over the North Atlantic Ocean in recent years. These systems present forecasting challenges because of their hybrid structure. The ...

Abstract: An empirical relationship between climatological sea surface temperatures (SST) and the maximum intensities of tropical cyclones over the eastern North Pacific Ocean is developed from a 31-yr sample (1963?93). This ...
