Changes in North American extremes derived from daily weather data

Global changes in seasonal means and extremes of precipitation from daily climate model data

[1] We investigate simulated changes of seasonal precipitation maxima and means in a future, warmer climate. We use data from the ESSENCE project, in which a 17-member ensemble of climate change simulations in response to the SRES A1b scenario has been carried out using the ECHAM5/MPI-OM climate model. The large size of the data set gives the opportunity to detect the changes of climate extreme...

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...

North American Weather-type Frequency and Teleconnection Indices

The impact of teleconnections upon the surface climate has largely been examined via a response in monthly mean temperature or total precipitation. In this paper, a different approach is undertaken, by examining the response of synoptic weather-type frequencies to different teleconnection phases. For over 330 stations in the USA and Canada, the Spatial Synoptic Classification scheme has classif...

U.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...
