Bayesian statistical models were developed for the number of tropical cyclones and the rate at which these cyclones became hurricanes in the North Atlantic. We find that, controlling for the cold tongue index and the North Atlantic oscillation index, there is high probability that the number of cyclones has increased in the past thirty years; but the rate at which these storms become hurricanes...

[1] New evidence based on recent satellite data is presented to provide a rare opportunity in quantifying the long-speculated contribution of tropical cyclones to enhance ocean primary production. In July 2000, moderate cyclone Kai-Tak passed over the South China Sea (SCS). During its short 3-day stay, Kai-Tak triggered an average 30-fold increase in surface chlorophyll-a concentration. The est...

The long-term goals are to understand how variabilities in the large-scale atmospheric environment and the internal tropical cyclone structure influence tropical cyclone track and intensity characteristics and define how these influences differ between developing, mature, and decaying tropical cyclones. During the initial stages of tropical cyclone development, structure and track characteristi...

Personal experience can influence our attitudes and actions concerning climate change. This paper examines the experience-perception link in relation to tropical cyclones using a distinctly revealed preference approach, mitigating biases of prior research in this area. Specifically, we study how people alter their internet searches related to climate change in response to tropical cyclones. Usi...

Extratropical cyclones are the primary natural hazard affecting western Europe. They are associated with strong winds and rainfall (Lamb, 1991) which can result in significant societal impacts. For example, windstorms Anatol, Lothar and Martin in 1999 resulted in approximately €16 billion of total insured losses (Swiss Re, 2016). Cyclones contribute to more than 70% of the precipitation that fa...

The optimised design of gas cyclones is of particular relevance for the recovery of highly valuable products, such as in the production of active pharmaceutical ingredients (API) through drying systems such as spray or fluid bed drying [1]. Traditionally, these have been captured with reverse flow gas cyclones, but fine and low density particles remain difficult to capture [2]. Bagfilters, alth...

Tropical cyclones (TCs, also known as hurricanes and typhoons) generally form at low latitudes with access to the warm waters of tropical oceans, but far enough off equator allow planetary rotation cause aggregating convection spin up into coherent vortices. Yet, current prognostic frameworks for TC make contradictory predictions climate change. Simulations past climates, such Eocene Pliocene, ...

Tropical upper-tropospheric troughs (TUTTs), also known as midoceanic troughs, are elongated troughs that appear in summer monthly averaged maps of the upper-tropospheric flow over the oceans. The transient part of these climatological features is composed of TUTT cells and their origin is the subject of this study. TUTT cells often occur to the east of tropical cyclones. A nonlinear shallow wa...

The transfer of upper kilometer water from the Indian Ocean into the South Atlantic, the Agulhas leakage, is believed to be accomplished primarily through meso-scale eddy processes. There have been various studies investigating eddies of the ‘‘Cape Basin Cauldron’’ from specific data sets. The hydrographic data archive acquired during the last century within the Cape Basin region of the South A...
