Wind anemometer studies how wind direction and speed affect precipitation
With the development of the global economy, energy consumption continues to increase, acidic pollutant emissions increase, and the acid rain problem becomes increasingly serious. People have controlled the discharge of acidic pollutants, but the phenomenon of acid rain still exists, and the harm it brings to humans is also increasing day by day. By measuring the precipitation and wind direction and speed in the west area of Jiangmen City, we can understand how meteorology affects rainfall. Among them, the wind direction and anemometer is a scientific instrument we need to use to record changes in the air at any time.
Through relevant data, we learned that the maximum weakening of acidity occurred on June 19, 2006, and the pH value increased by 1.10. This precipitation lasted for 2 days. On the second day, the wind direction changed to SW. The wind direction in this direction was underdeveloped. On the first day, the wind direction changed to SW. The SSW wind of 1.1m/s on the day brought clean and moist air over the South China Sea into the inland. With the precipitation of up to 83.4mm that day, the sulfur dioxide concentration that day dropped by 0.015mg/L compared with the previous day. The next largest value occurred on August 22, 2005, when the pH value increased by 1.08. The precipitation lasted for 7 days, which was the longest continuous precipitation in the past 3 years. The acidity of this precipitation fluctuated greatly; the wind speed ranged from 2nd to 6th. The weather is close to 0 and the wind frequency is still, which is mainly caused by the emission of local acidic pollutants. The temperature and air pressure are increasing day by day, and the air flow is dominated by updrafts. The continuous precipitation in the first four days has a strong scrubbing effect on the air near the ground, making the air cleaner. On the fifth day, the precipitation suddenly increases to 33.7mm, and with The average wind speed that day was 0, the surrounding acidic substances were limited to be replenished, and the precipitation acidity was significantly weakened; but the precipitation on the 6th day was significantly reduced, only 4.1mm. The warm and humid S direction wind brought acidic pollutants to be replenished, and the near-ground air humidity The chemical reaction is strong, and the precipitation acidity suddenly increases by 0.81. From the continuous precipitation analysis in the past three years, it can be seen that the E to SE, S and SW azimuth winds with larger wind speeds, especially typhoons, bring clean near-surface air formed on the ocean surface. Clusters will weaken the acidity of precipitation. The SSE azimuth wind with smaller wind speed transports industrial polluted air masses upstream over a short distance; the ENE azimuth wind with higher wind speed transports industrial polluted air masses upstream over long distances, and chemically reacts with near-ground air masses with higher humidity along the way. , the enrichment of acidic pollutants gradually increases the acidity of precipitation. In addition, in meteorological measurement, we often use small weather stations, because this instrument can measure up to 11 parameters and is comprehensive.
Meteorology is the environment we live in every day, such as the daily weather forecast of cloudy, sunny, rainy, windy, etc., which we can feel every day, but in the meteorological detection department, we need regular instruments , such as automatic field microclimate observers, wind direction and speed monitors, etc., used to specifically detect wind speed, wind direction, or parameters such as temperature, humidity, illumination, and dew point.
