Geography essay of 400 words: Introducing the climate characteristics of Beijing and its impact on production and life in Beijing.
Beijing Climate Overview
The Beijing area spans 115 degrees 25 minutes east longitude - 117 degrees 30 minutes east longitude, 39 degrees 28 minutes north latitude - 41 degrees 05 minutes north latitude, and is surrounded by mountains on three sides. , the average altitude of the ridge is about 1,000 meters, and the mountains on three sides form an arc-shaped natural barrier. The piedmont plain area is close to the mountains and the sea, and the terrain is a gradient from southeast to northwest. Beijing has a warm temperate semi-humid and semi-arid monsoon continental climate. It has the distinctive characteristics of cold winters with less rain and snow, strong winds and low humidity in spring, hot summers with concentrated rain, and cool autumns with sufficient sunshine, and there are obvious regional differences. Because it is located in a zone where warm and cold air meet, annual precipitation changes greatly, and meteorological disasters such as drought, heavy rain, strong winds, hail, and cold waves occur frequently.
Climate characteristics of Beijing in each season
1. Spring (March-May): Temperatures are changeable and rise and fall quickly, and there are often strong winds to cool down.
Number of windy days Accounting for 36% of the number of windy days throughout the year. The precipitation is 45---80 mm, accounting for about 10% of the annual precipitation. Evapotranspiration accounts for 30-32% of the annual evapotranspiration. Due to the rapid temperature rise, low humidity and strong evapotranspiration, and dry soil, strong winds and dusty days often occur, and the temperature rises quickly after the wind. This is a characteristic of Beijing’s continental climate.
2. Summer (June-August): Hot and rainy weather is a prominent feature. The average temperature in July is about 26 degrees in plain areas, and between 22 and 25 degrees in most mountainous areas. The precipitation is between 400-600 mm, accounting for about 75% of the annual precipitation. The precipitation is unevenly distributed in Zaoshulin and Badaohe in Huairou County, Manshui River in Fangshan, and Luoying, Haizi and Jiangjungguan in Pinggu Town. , a rainy area. Seasonal precipitation is over 600-700 mm. In the mountainous areas north of Kangzhuang and Zhangshanying in the northwest mountainous area, the seasonal precipitation is less than 400 mm, and the precipitation intensity is high. Often, several heavy rains or one or two heavy rains are equivalent to the monthly precipitation.
3. Autumn (September-November): Suitable temperature and humidity, sunny and warm with little rain are the characteristics of this season.
Seasonal precipitation only accounts for 14% of annual precipitation. The rapid cooling makes the duration of autumn shorter than that of spring. At the end of autumn, a strong cold air moves southward and winter enters.
4. Winter (December-February): cold and dry, windy and snowy, and a long season are the characteristics of this season. The average monthly temperature is below zero, and the precipitation is only about 10 mm, accounting for 2% of the annual precipitation. Wind and cold waves occur every year, but their intensity and frequency vary.
