Based on in-situ time series data from an array of temperature sensors and an acoustic Doppler current profiler on the continental shelf of the northwestern South China Sea, a sequence of internal solitary waves (ISWs) were observed during the passage of tropical storm Washi in the summer of 2005, which provided a unique opportunity to investigate the ISW response to the tropical cyclone. The p...

Additional experiments with the slowly varying axisymmetric hurricane model described by Anthes are presented. Variable horizontal eddy viscosity coefficients are utilized to study circulations that result from an increased heating function and a heating function with a double maximum along the radial direction. Infrared radiative cooling is modeled for the clear tropical atmosphere following S...

The 1998 Sydney-Hobart yacht race was affected by storm-force winds on the afternoon of 27 December 1998. Of the 115 yachts that contested the race, 71 retired, six were abandoned, and five sank. Fifty-five crew were rescued, and six lives were lost (see Cruising Yacht Club of Australia (CYCA) 1999). These storm-force winds were associated with a mesoscale extratropical cyclone that developed d...

Results from an explicit simulation of tropical cyclones are presented in this study. The numerical model used in the study is the triply nested movable mesh primitive equation model newly developed by the author. It uses the hydrostatic primitive equations with explicit treatment of cloud microphysics. The integration domain is triply nested by a two-way nesting strategy with the two interior ...

With the multitude of cloud clusters over tropical oceans, it has been perplexing that so few develop into tropical cyclones. The authors postulate that a major obstacle has been the complexity of scale interactions, particularly those on the mesoscale, which have only recently been observable. While there are well-known climatological requirements, these are by no means sufficient. A major rea...

In the Tropics more small drops and less large drops were found in oceanic precipitation than in continental precipitation at the given reflectivity. Similarly, more small drops and less large drops were found in remnants of a tropical cyclone than in frontal precipitation in mid-latitude site at the same reflectivity. The presence of small drops was higher in deep convective regime than in str...

A new product for estimating the 24-h probability of TC formation in individual 58 3 58 subregions of the North Atlantic, eastern North Pacific, and western North Pacific tropical basins is developed. This product uses environmental and convective parameters computed from best-track tropical cyclone (TC) positions, National Centers for Environmental Prediction (NCEP) Global Forecasting System (...
