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...

Hydropower has now become the best source of electricity on earth. It is produced due to the energy provided by moving or falling water. History proves that the cost of this electricity remains constant over the year. Because of the many advantages, most of the countries now have hydropower as the source of major electricity producer. The most important advantage of hydropower is that t is gree...

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...

Tropical cyclones and storms, hurricanes, powerful thunderclouds, which generate tornadoes, destructive ex-tratropical cyclones, which result in catastrophic floods, are the powerful cloud systems that contain huge amount of water. According to the hypothesis argued in this paper, an electric field coupled with powerful clouds and electric forces play a cardinal role in supporting this huge mas...

Arctic cyclone activity is analyzed in 11 year (2000–2010), 3-hourly output from the Arctic System Reanalysis (ASR) interim version. Compared to the global modern era reanalyses (European Centre for Medium-Range Weather Forecasts Reanalysis (ERA)-Interim, Modern Era Retrospective Analysis for Research and Applications, and National Centers for Environmental Prediction-Climate Forecast System Re...
