Read the chart below and answer the questions. (1) Analyze the climate statistical data of Yucheng, and explain the tables of wind, temperature and precipitation in this area.

(1) windy weather in spring; The annual temperature is high; Precipitation is concentrated in July and August.

(2) The upper reaches originate from mountainous areas, and the river flows too fast; The downstream plain is low and flat, with many depressions and poor drainage; Summer precipitation is concentrated and there are many heavy rains; The water system is fan-shaped, with tributaries entering the flood season at the same time, and the main stream entering the sea alone, which makes the water level soar; Poor vegetation coverage and high sediment concentration in the river channel cause siltation and poor flood discharge.

(3) Haihe River, Luanhe River and Yellow River

(4) Earthquake disasters may occur, because this area is on the edge of the Pacific Rim plate boundary (volcanic earthquake) zone; There are many faults (fault zones) in the underground strata in this area.
