Changing Coastal Weather and Extremes
Hardly any area in the whole world is undergoing such dynamical environmental and social change as the coastal regions of the world. Approximately 20% of the world’s human population live within 30 km of the sea, and nearly double that number live within the nearest 100 km of the coast (IPCC 2001). Furthermore, a big part of economic activities is going on in these areas. In the coastal environ...
متن کاملU.S. weather extremes and El Niño
40 A global coupled climate model representative of the current generation of models is 41 shown to simulate most first order aspects of El Niño events, their teleconnections over 42 North America, and the associated observed patterns of extremes in present-day climate. 43 Future El Niño teleconnection patterns over the U.S. are projected to shift eastward and 44 northward due in part to the di...
متن کاملSpatial extreme value analysis to project extremes of large-scale indicators for severe weather
Concurrently high values of the maximum potential wind speed of updrafts (Wmax) and 0-6 km wind shear (Shear) have been found to represent conducive environments for severe weather, which subsequently provides a way to study severe weather in future climates. Here, we employ a model for the product of these variables (WmSh) from the National Center for Atmospheric Research/United States Nationa...
متن کاملWCRP Grand Challenge: Understanding and Predicting Weather and Climate Extremes
Weather and climate extremes are an inherent part of climate. There is overwhelming evidence that the climate and its extremes are changing. As extremes affect every aspect of our society, decisionand policy makers, and stakeholders are increasingly asking for reliable predictions of extremes on time scales from days to seasons and centuries. To meet this societal need, the world climate resear...
متن کاملCaution needed when linking weather extremes to amplified planetary waves.
The Northern Hemisphere mid-latitudes have experienced frequent summer weather extremes in the last decade (1-2). In a recent PNAS paper, Petoukhov et al. (3) propose a single physical mechanism that could help explain the occurrence of these weather extremes. They suggest that such extremes are associated with well-developed synoptic-scale planetary waves, in particular large amplitude quasi-s...
