Sea level is rising and will continue to rise as oceans warm and glaciers melt. Rising sea level means higher storm surges, even from relatively minor storms, which increases ... http://www.tstorms.info/?p=37   Given the high degree of interest in the possible relationship between climate change and tropical cyclones (including hurricanes and typhoons), a new summary statement on the topic has been developed by the global community of tropical cyclone researchers and forecasters as represented at the 6th International Workshop on Tropical Cyclones ... http://www.tstorms.info/?p=31 The relationship between global lightning frequencies and global climate change is examined in this thesis. In order to study global impacts of climate change, global climate models or General Circulations Models (GCMs) need to be utilized. Since these models have coarse resolutions many atmospheric phenomena that occur at subgrid scales, ... http://www.tstorms.info/?p=30 The global electrical circuitThe Earth’s surface, ocean and solid, and the ionosphere are both highly conductive. The atmosphere conducts electricity because of the presence of positive and negative ions plus free electrons. Conductivity is poor near sea level but increases rapidly with height up to the ionosphere, also it is ... http://www.tstorms.info/?p=29  When you think of lightning, you think of a thunderstorm. Many people also assume that hurricanes have a lot of lightning because they are made up of hundreds of thunderstorms. http://www.tstorms.info/?p=28 Atlantic hurricane activity has increased significantly since 1995 , but the underlying causes of this increase remain uncertain. It is widely thought that rising Atlantic sea surface temperatures have had a role in this, but the magnitude of this contribution is not known. Here we quantify this contribution for storms ... http://www.tstorms.info/?p=26 The proximity in time and space of consecutive lightning flashes in thunderstorms was first studied by Mazur (1982) who termed the phenomenon "associated lightning discharges". These flashes were reported to occur in multi-cell storms, where several electrically active cells (EACs) co-exist in the same mesoscale region. VHF radar observations showed ... http://www.tstorms.info/?p=24 Recent years have shown the tremendous damage and loss of life that can be caused by Atlantic Basin hurricanes. The majority of these hurricanes start as African easterly waves (AEWs) over the African continent. In this paper we provide evidence showing the connection between lightning activity over eastern Africa, and ... http://www.tstorms.info/?p=14  The Mediterranean Israeli dust experiment (MEIDEX) flew on-board the space shuttle in winter 2003, in a 39°-inclination orbit for 16 days, passing over the major thunderstorm regions on Earth. The primary science instrument of the MEIDEX payload is a Xybion IMC-201 image-intensified radiometric camera with six narrow band filters, boresighted ... http://www.tstorms.info/?p=13
