abnormal flood
1.Result it is the determinant cause leading abnormal climate of Shaanxi during Main-flood Season that Blocked High near Ural Mountain and Balkhash Low are stable in motion and subtropical high is strong.
2.THE NUMERICAL EXPERIMENT ON EFFECT OF ATLANTIC HEATING AND THE RELATIONSHIP BETWEEN THE ABNORMAL CIRCULATION OF PRECEDING STAGE ON THE DROUGHT AND FLOOD IN THE HETAO HUABEI REGION AND ATLANTIC SSTA
3.By analyzing 500 hPa height field data in 1961_2002, it is found that the dipole index of sea temperature over eastern/western Indian Ocean has a close relation to the abnormal of Eurasia 500 hPa height field of Northern Hemisphere, which affects on the variation of precipitation and temperature of flood period over Qinghai-Xizang Plateau throush the strong and weak of Indian southwest monsoon.
4.In design of the flood releasing structures,in addition to optimization of the design parameters and reasonable determination of the structural figuration of the surface sluices and bottom outlets, an abnormal distored deflecting bucket and a continuous deflecting bucket are provided for the right and left ski jump spillway respectively.
