Trend distribution of the extreme precipitation and temperature events under climate change condition in 1901 - 2012 and regional differences of extreme events' frequency in the relatively warmer or colder periods are analyzed by defining the 10th or 90th percentile as the threshold of extreme events for each grid based on the CRU TS 3.22 datasets, focusing on the accelerated warming period from mid-late 1970's to late 1990's and the global warming hiatus (1998 - 2012). The results show that the frequencies of the extreme severe precipitation events and the extreme high temperature events increase while the frequencies of the extreme low temperature events decrease under significant global warming condition in the last 112 years. Frequency distribution of summer extreme severe precipitation events in the accelerated warming period is similar to that in 1956 - 1976 and high values are in North American mid-high latitudes, South America and Eurasian low latitudes. North American mid-high latitudes become low-value areas while frequencies in Eurasian mid latitudes increase in the warming hiatus. High values of frequency of winter extreme severe precipitation events are in northern South America, Eurasia and western Oceania while North America and southern Africa become low-value areas in the global-warming hiatus. Frequencies of the extreme high temperature events increase in warmer periods and mid-eastern Eurasian areas have high values in winter in the accelerated warming period. The feature of the extreme low temperature events is opposite to the extreme high temperature events but the frequency in Eurasian mid latitudes in the relatively warmer period of 1931 - 1955 is higher than the coldest period of 1901 - 1930 and the relatively colder period of 1956 - 1976. Frequencies of the extreme low temperature events increase obviously in northwestern Oceania in summer and winter and Eurasian mid-high latitudes in winter in the warming hiatus compared to that in the accelerated warming period. These results reveal the regional differences of land extreme precipitation and temperature changes in different periods, and the possible mechanisms still need further study.
