Red and red river weather

Landform of Laibin City: the eastern flank of Dayao Mountain, the arc-shaped mountain in the northeast of Guangxi, and the dome-shaped mountain in the north of Liu Bei. The mountains are arranged north and south, with the front ridge of one mountain extending south and the western mountainous area being arranged in a northwest arc; Central plains and terraces. The water system is dendritic and the outlet is southeast. The whole terrain is roughly from north to south, with high, medium and low around, and the lake is slowly inclined from northwest to southeast.

Climate: Laibin City is located in the subtropical monsoon climate zone in central Guangxi, with monsoon circulation and warm and humid maritime air quality prevailing in summer. Therefore, summer is long, and in the rainy season of the same season, the vertical difference latitude between winter and spring is greater than that in spring, but the difference is lower than that in autumn, and the heat in winter and spring is insufficient; Regional differences of climate resources. Or more commonly, it is affected by the warm and humid airflow in the southwest and the cold air quality in the north, such as drought, rainstorm, flood and hail, lightning, low temperature (freezing), victims and other disastrous weather.

Hydrology: In 2004, except for a few stations, the average precipitation was high, and the annual precipitation of most stations was higher than the multi-year average 10, even higher than the normal 2 stations. The hydrological runoff station site in Laibin City has been very small this year. The annual precipitation is the largest in the site, with annual precipitation 1% 3.5mm, rainy days 162 days: the minimum precipitation is 28.6%, which is the same as last year, and the average annual precipitation 10HO mm is less than normal. All precipitation is mainly concentrated in May-July, and the highest precipitation is concentrated in July and the driest month 10. Distribution of precipitation in rainfall stations along clever areas: the high-value area of rainfall and rainstorm is 1963.5mm in Tongyou Red Precipitation in Jinxiu Yao Autonomous County and 68.5mm in Jinxiu along Dayaoshan in Lanling Poling City of Xingbin, and the two low-value areas are Xincheng County and Oudongguo, so the rainfall in rainfall stations in Zhong Ping District of Xiangzhou District is1055.3mm..
