摘要许多研究表明，在人为全球变暖的影响下，热浪的频率、强度和持续时间都会增加。然而，在地形复杂和水陆反差巨大的地区，人们对极端高温和温度分布的变化一般了解较少。这种表面变化在美国西北部很重要，那里的天气和中尺度环流与当地地形和陆地水界面相互作用，产生热浪，对火灾天气、空气质量、风能和一般人口产生重大影响。因此，它是至关重要的，以确定如何天气和中尺度环流，驱动这样的地方极端将在一个变暖的world.This文件中的变化，分析了与美国西北部地区的极端高温的条件，利用全球和区域气候模式。700百帕变暖的最大值预计在美国西北部和加拿大西南部，低层变暖...
AbstractA number of studies have suggested that heat waves will increase in frequency, intensity, and duration under anthropogenic global warming. However, changes to heat extremes and temperature distributions in general are less understood in regions of complex terrain and substantial land–water contrasts. Such surface variations are important in the northwest United States, where synoptic- and mesoscale circulations interact with local topography and land–water interfaces to produce heat waves that have substantial impacts on fire weather, air quality, wind energy, and the population in general. Thus it is crucial to identify how the synoptic- and mesoscale circulations that drive such local extremes will change in a warming world.This paper analyzes changes to the conditions associated with heat extremes over the northwest United States by utilizing global and regional climate models. A maximum in 700-hPa warming is projected over the northwest United States and southwest Canada, with low-level warmin...
