warm period
5.The source of the Tsushima Warm Current during the period of June, 1986 to December, 1988 has been primarily studied with a two dimensional numerical model. The simulation results show three basic patterns for the source of the Tsushima Warm Current: 1. the water of the Tsushima Warm Current in the East China Sea is composed mainly of the part of the Kuroshiogoing northward;
9.Comparison and study of the biotic characters in the Jinggu and Longchuan basins in Yunnan Province show that: (1)the two basins underwent the developing period, expanding period and shrinking period from early Miocene Epoch to Pliocene Epoch; (2)the climate in the region was dry in early Miocene Epoch, warm and humid in middle-late Miocene Epoch and dry in Pliocene period; (3)the basins expanding in middle-late Miocene Epoch formed a semi-deep-lake to deep-lake environment.
