Using the standardized data of the extreme high temperatures in summer from 1960 to 2007 of 34 meteorological stations in Chongqing,the spatial distributional and temporal evolution of extreme high temperatures in June-August in the 48 years are studied with EOF and REOF analyses.

The probability distribution model of annually extremely lowest climate temperature of Yong an City was set up by applying the first model extreme distribution in the extreme theory and using the basic data of meteorological observation of Yong an City from 1971 to 2005.

By using the data of geography provided by Digital Fujian Project and establishing model which calculated the value of annual extreme minimum temperature,the map of spatial distribution about mean annual extreme minimum temperature was intuitively represented with 50 m×50 m resolution by GIS.

The selection of measurement time should consider that the extreme maximum soil temperature lags behind the maximum air temperature, and be determined by reference to the meteorological history data.

Analysis on feature of extreme temperature change in Ningxia in recent 40 years;

By the use of the death data from the investigation among over 250,000 people with ages from 25 years old to 74 years old in the period of 1994-2000 in Beijing urban and suburb areas provided by Beijing Institute of Cardiopulmonary and Vascular Disease,and the daily and monthly mean climate data in Beijing,the effects of extreme temperature on urban human death are analyzed.

Emphasized the need to study the thermal conditions in air-conditioned building under extreme temperature conditions.
