| The Influence of the Expansion of the West Pacific Warm Pool on the Climate Change in the North China Plain |
| Two great abrupt warming events have been recognized from the Guanjiabao drill hole in Huanghua County,Hebei Province,North China Plain.The first warming event began about 40000a B.P.(during the Cangzho transgression);the second started in 10000a B.P.(during the Tianjin transgression).Both events are the same as the global warming events in the time scale.The mean temperature was 7℃ higher than the present temperature during the first warming event,and 13℃ higher than the former cooling event(in the regression period between the Baiyangdian transgression and the Cangzhou transgression)in the northeastern part of Nroth China Plain.The expansion of the Western Pacific Warm Pool may be responsible for the significant warming up events in the North China Plain. The mean temperature was 2～3℃ higher than the present temperature during the second warming event. |
