A numerical experiment for the study of the development and the structure of tropical cyclones is performed with a 13-layer model. The total amount of latent heat released in a vertical column of air is specified by the horizontal mass convergence in the friction layer, as proposed by Ooyama (1964) . The vertical distribution of released latent heat is assumed to be proportional to the temperat...

Using Moderate Resolution Imaging Spectroradiometer and an extratropical cyclone database, the climatological distribution of aerosol optical depth (AOD) in extratropical cyclones is explored based solely on observations. Cyclone-centered composites of aerosol optical depth are constructed for the Northern Hemisphere midlatitude ocean regions, and their seasonal variations are examined. These c...

For generations, cyclones and tidal surges have frequently devastated lives and property in coastal and island Bangladesh. This study explores vulnerability to cyclone hazards using first-hand coping recollections from prior to, during and after these events. Qualitative field data suggest that, beyond extreme cyclone forces, localised vulnerability is defined in terms of response processes, in...

Figure 1. Mauritius Larval Source Management (LSM) in Mauritius Malaria was first introduced to the island of Mauritius from mainland Africa during the mid 19 century [1]. Over a century of malaria control campaigns ensued, including large indoor residual spraying (IRS) operations and widespread larval source management (LSM) projects [2]. Mauritius was declared malariafree in 1973 by the World...
