I have four long-term goals. My first goal is to finalize the large body of work already carried out by the PI on the predictability of tropical cyclone (TC) forecast tracks out to 72 hours ahead. My second goal is to apply similar, as well as new, ideas to the predictability of forecast intensity out to 72 hours ahead. My third goal is to carry out observing system simulation experiments (OSSE...

In the context of Multiple criteria decision analysis, we present the necessary and sufficient conditions to represent a cardinal preferential information by the Choquet integral w.r.t. a 2-additive capacity. These conditions are based on some complex cycles called cyclones.

The separation of solid particles from gas-solid process streams is an important unit operation in many chemical processes. Out the different types equipment that are used for separation, cyclone separators widely their operational flexibility, efficiency and capital cost. This study focused on design optimal configuration several cyclones a fertilizer plant. granulation step plant leads to usi...

cated on the coast and 44% of the world’s population lives within 150 km of the ocean.1 Unfortunately, coastal regions are often low-lying and thus susceptible to an increase in seasurface elevation. A storm surge is a potentially devastating rise in the sea surface caused by extratropical cyclones or by tropical cyclones such as hurricanes and typhoons. Surges can lead to large loss of human l...

The modern Great Barrier Reef (GBR) is part of the world’s largest and best known mixed terrigenous-carbonate continental margin. The GBR shelf contains three shore-parallel sedimentary belts: an inner shelf zone of terrigenous sedimentation at depths of 0–22m; a middle shelf zone of sediment starvation at depths of 22–40m; and an outer shelf reef tract with its inner edge at ca. 40m depth. The...

A survey of mesoscale cyclogenesis near the Antarctic peninsula has been carried out for 1991 based on digital satellite imagery collected at Palmer Station. Slightly higher cyclonic activity was found over the Bellingshausen Sea sector (BSS) than in the Weddell Sea sector (WSS). Both sides were characterized by a pronounced formation maximum in summer and a minimum in winter. Comma clouds were...

Damages that can be caused by meteorological phenomena, particularly tropical cyclones, pose a major financial risk to insurance and reinsurance companies. It is therefore necessary for these companies to assess the frequencies and intensities of tropical cyclones hitting areas with insured objects as precisely as possible to estimate their losses. The approach taken in this paper is to create ...

High-vertical-resolution rawinsondes were used to document the existence of low–bulk Richardson number (Rb) layers in tropical cyclones. The largest frequency of low Rb existed in the inner 200 km at the 13.5-km level. This peak extended more than 1000 km from the storm center and sloped downward with radius. The presence of an extensive upper-tropospheric low-Rb layer supports the assumption o...

The polar cyclone at Jupiter's south pole and the five cyclones surrounding it oscillate in position interact. These cyclones, observed since 2016 by NASA's Juno mission, present a unique opportunity to study vortex dynamics interactions on long time scales. cyclones' data, acquired Juno's JIRAM instrument, is analyzed, showing dominant oscillations with ~12 month periods amplitudes of ~400 km....

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...
