When averaged daily extreme high temperature in summer increases 3.0℃,the probability will rise from 0.13 to 0.2～0.3, it means the days that daily extreme high temperature is equal or greater than 35 ℃ will rise from 12 now to 20～30 in the future.
Using the extreme high and low monthly temperatures of 20 stations in Ningxia during 1961-2004,the basic features of the extreme temperature change were analyzed with climate trend index and Mann-Kendall mutation test. Results showed that,the annual extreme high and low temperatures during this period rose with fluctuation,and the rising range of annual extreme low temperature exceeded that of extreme high temperature;
It was showed that the monthly mean daily maximum temperature and the frequency of extreme high temperature mostly caused the variation of mean temperature, when the maximum temperature was influenced by the solar radiation.
Compared the spacial features for the estival extreme high temperature and the hot days in Shandong Province from 1961 to 1990 with that from 1971 to 2000,it indicates that there is evident regional difference for the Climatic change of it,the hot days in the eastern increased but decreased in the western.
These findings suggest that elevated CO2 could promote photosynthetic activity during critical periods of seedling establishment, and enhance the potential for L.?tridentata to survive extreme high temperature events.
Effects of extreme high temperature, drought and elevated CO2 on photosynthesis of the Mojave Desert evergreen shrub, Larrea tri
This method has been used in this study to assess the resistance to extreme high temperature in two bean varieties, Barbucho (Chilean, non commercially bred) and Blue lake (commercially available in the UK).
Flowering, boll/lint production, and product effectiveness were tested under extreme high temperature conditions that existed during 2003.
