ice action
2.Due to the influence of Siberia monsoon in the Yellow River Basin, the winter is dry and cold with little rainfall and river flow is relatively low, thus many river sections are frozen and may be flooded by ice jams under the action of multi factors of temperature, flow and features of river courses.
9.By using the data such as the relative sunspot number, the temperature anomaly in Lhasa, the SSTA in relative region and the informationon th sea ice area in South Pole, the relationship between the annual frequency of tropical cyclone affecting Guangxi and the activity of sunspots, the heat status of Tibetan Plateau, the action of ocean and the aberrance of sea ice in the prior period in South Pole is computed and analyzed, on the basis of which the conceptual prediction model is set up.
