Using General Circulation Models (GCMs) for tropical cyclone studies is difficult due to the relatively small size of the storms, the intense convection and multitudes of large-scale small-scale interactions. These are mostly unresolved at typical GCM resolutions of about 50-100 km, and still challenged at high resolutions between 12-30 km. Nevertheless, high-resolution GCMs are becoming a tool...

Tropical cyclone Tracy (Tracy) remains one of the most destructive natural hazard events in Australia’s history. Growth in the population and size of Darwin since 1974 makes it desirable to know what impact an event similar to Tracy would have on the present day built environment. To assess the impacts in 1974 and the present day, we apply the Tropical Cyclone Risk Model (TCRM) developed at Geo...

[1] The record of past tropical cyclones provides an important means to evaluate the hurricane hazard. Historical chronologies are a source of information about tropical cyclones prior to the modern era. Chenoweth (2006) describes an archive of 383 tropical cyclones occurring during the eighteenth and nineteenth centuries, largely before the official hurricane record. The present study demonstr...

The sensitivity of tropical cyclone intensity to ventilation of cooler, drier air into the inner core is examined using an axisymmetric tropical cyclone model with parameterized ventilation. Sufficiently strong ventilation induces cooling of the upper-level warm core, a shift in the secondary circulation radially outward, and a decrease in the simulated intensity. Increasing the strength of the...

Daily flow records, rainfall data and tropical cyclone maps during 19701998 are used to document the impact of tropical cyclones (TCs) on floods in the Rewa River system, Viti Levu, Fiji. Floods are large, brief, isolated events caused by TCs and non-TC tropical rainstorms. More floods are caused by tropical rainstorms than by TCs, but TC floods are larger. The log Pearson Type III distribution...

Uncertainty represented in visualizations is often ignored or misunderstood by the non-expert user. The National Hurricane Center displays hurricane forecasts using a track forecast cone, depicting the expected track of the storm and the uncertainty in the forecast. Our goal was to test whether different graphical displays of a hurricane forecast containing uncertainty would influence a decisio...

An ingredients-based approach (e.g., Johns and Doswell 1992) is used in the operational prediction of tornado threat, regardless of whether the favorable environment results from midlatitude or tropical perturbations. Since the majority of tropical cyclone (TC) tornadoes are associated with supercells (Edwards et al. 2012a; hereafter E12), the forecaster typically can focus on the same ingredie...

INTRODUCTION Humanitarian aid provision and early medical response missions to areas ravaged by natural disasters are as essential nowadays as in the past, and medical personnel play a pivotal role in these delegations. CASE DESCRIPTION In November 2013, tropical cyclone Haiyan (Yolanda) slammed the Philippines archipelago, leaving more than an estimated 6000 dead in its wake while demolishin...

[1] A study of tropical storm activity in the southern South China Sea region was carried out for the period of 1960 to 2006 using data obtained from the UNISYS website archive, which was provided to them from the Joint Typhoon Warning Center (JWTC) best track data. This study was motivated by two particularly costly storms that impacted Malaysia during the 1996–2001 period. This study demonstr...
