Contingent productivity responses to more extreme rainfall regimes across a grassland biome
Climate models predict, and empirical evidence confirms, that more extreme precipitation regimes are occurring in tandem with warmer atmospheric temperatures. These more extreme rainfall patterns are characterized by increased event size separated by longer within season drought periods and represent novel climatic conditions whose consequences for different ecosystem types are largely unknown....
متن کاملObserved trends in extreme precipitation events in China during 1961–2001 and the associated changes in large-scale circulation
[1] The observed trends in extreme precipitation events, and those in annual and seasonal mean precipitation in China during 1961–2001 are analyzed. The results show that the annual mean precipitation increases significantly in southwest, northwest, and east China, and decreases significantly in central, north and northeast China. The increasing trends in east China occurred mainly in summer, w...
متن کاملDetectability of anthropogenic changes in annual temperature and precipitation extremes
This paper reports on a study of temperature and precipitation indices that may be suitable for the early detection of anthropogenic change in climatic extremes. Anthropogenic changes in daily minimum and maximum temperature and precipitation over land simulated with two different atmosphere-ocean general circulation models are analyzed. The use of data from two models helps to assess which cha...
متن کاملAnalysis of inter-decade changes in trends and spatial patterns of annual and seasonal precipitation, case study: West of Iran
The present research about the spatial changes of precipitation is mainly focused on western areas of Iran. Precipitation data for three seasons of fall, winter, and spring have been obtained from Esafzari Database, with 15*15 km spatial resolution in the form of a Lambert Cone Image System for the period from 1986 to 2015. To examine the prevailing pattern of precipitation in west of Iran, we ...
متن کاملبررسی اثر تغییر اقلیم بر روند نمایه های حدی بارش ایران زمین
Global changes in extremes of the climatic variables that have been observed in recent decades can only be accounted anthropogenic, as well as natural changes. Factors are considered, and under enhanced greenhouse gas forcing the frequency of some of these extreme events is likely to change (IPCC, 2007 Alexander et al., 2007). Folland et al. (2001) showed that in some regions both temperature a...
