The influence of El Niño/Southern Oscillation (ENSO) on tropical cyclone (TC) activity in the western North Pacific (WNP) is investigated using a high-resolution atmosphere-ocean Coupled General Circulation Model (CGCM) developed by the National Research Institute for Earth Sciencie and Disaster Prevention. The CGCM simulation indicates the model TC activity associating with the ENSO as follows; (1)the frecuency of model TC in the WNP during the ENSO cold phase is slightly higher than during the ENSO warm phase (2)the genesis loction of model TC shifts eastward during the ENSO warm phase, (3)model TC tends to migrate westward during the ENSO warm phase and northward during the ENSO cold phase. These results are intimately related to variations in atmospheric circulaton and SST during the ENSO. Similar influences are also confirmed in the relationship between actual TC activity and actual ENSO. (AU)

This article of the bulletin is based on the analysis of data collected up until September 30th, 1999, and presents the definitive prognosis for food security during the lean season 99-00. It represents a re-evaluation of the first forecast (preliminary prognosis) conducted in May 1999, taking into consideration the relative importance and development of second season crops, as well as indicators of monetary incomes, compared to the structural potential of each district. The definitive prognosis for the 99-00 food security situation confirms, except for few districts, the first predictions expressed in May (preliminary prognosis) during the preliminary prognosis and is summarised by regions as follows: Northern Region, Central Region and Southern Region. The updated projection presented here indicates that a maximum of 77.740 individuals might be in need of some food assistance to avoid significant malnutrition in the leaning period now beginning. The food deficit for this group should not exceed the blobal amount of 1.119 tonnes of cereals

El período lluvioso en Venezuela se prolonga por ocho meses, abril a noviembre. En 1999 las lluvias que empezaron el 29 de novienbre hasta el 18 de diciembre intensificandose durante los días 15 y 16 diciembre, las lluvias caídas en estas fecha fueron de naturaleza estacionaria, cayeron sobre terrenos saturados, lo cual desencadenó en deslizamientos y derrumbres en múltiples cuencas del la Cordillera de la Costa, predominantemente en las del flanco norte por lo que el país sufrió daños e inundaciones que causaron pérdidas importantes: puentes caídos en Barquisimeto, desbordamiento de ríos de Miranda, pérdidas de viviendas, edificios, destrucción de carreteras en múltiples localidades. El documento tiene los siguientes objetivos: Recoger información sobre los efectos en zonas habitadas a nivel nacional, así como las estimaciones de pérdidas económicas directas, adelantar un diagnóstico sobre el origen y los mecanismos que generan avalanchas como las sucedidas en el norte de la Cordillera de la Costa y presentar recomendaciones y lineamientos generales para la mitigación

Severe weather associated with thunderstorms (tornadoes, hail, high winds, and flash floods) is reviewed with emphasis on the processes that are responsible. The basis for forecasting severe thunderstorms in reviewed. The parts of the world that are most vulnerable to various kinds of severe weather and the nature of the threats are described. The current state of the climatology of severe thunderstorms and problems and importance of improving climatological information are described. The lack of high-quality climatological information makes it very difficult to determine differences in event occurrence during different periods of the El Niño-Southern Oscillation (ENSO) in most of the world and almost impossible to detect changes associated with global climate change. It is argued, however, that the threats from severe thunderstorms are generally underestimated in many parts of the world. In genera, the effects of severe local storms are concentrated in a small number of events. Death tolls and damage in "average "years are typically smaller than the totals from individual events in other years. As a result, maintaining public awareness and preparedness activities is difficult since the threat of rare, extremely damaging events, is small at any individual location and time. (AU)

One of the major natural marine hazards on the globe is the storm surge phenomenon. Large storm surges with amplitudes of up to several meters generated by tropical cyclones occur in many areas of the world, including the Gulf of Mexico and the Northern Indian Ocean. The storm surges in the marginal seas of the North Indian Ocean are discussed here. These marginal seas include the Bay of Bengal, the Arabian Sea, the Persian (Arabian) Gulf and the Red Sea. Since storm surge prediction also involves tides, some tidal regimes are also discussed. Finally, some comments are made on the possible influence of the greenhouse warming and the El Niño phenomenon on storm surges. (AU)

An overview is provided of the impacts of tropical cyclones and of the activities that have occurred during the IDNDR to help ameliorate these impacts. The focus is on WMO and ICSU activities and their major international activities and achievements. A discussion is provided on tropical cyclone impacts, the WMO and ICSU programs during the decade, major related research programs and efforts to reduce the impacts of tropical cyclones. An outlook for the next decade completes the essay. (AU)
