Kneel for the topic of meteorological composition 1000 words or more. .
We went to the Meteorological Observatory by bus and started the interview. The staff uncle first introduced us to some natural disasters, including typhoons, which are storms with a radius of several hundred kilometers, and the radius has been several hundred kilometers, showing how big the disaster is; When a typhoon comes, heavy rain is often accompanied by heavy rain. In areas where typhoons pass, rainfall of 1.50 mm ~ 300 mm can generally be produced, and a few typhoons can produce torrential rain of 1000 mm or more. Flood refers to the phenomenon that the water contained in rivers, lakes and oceans rises and exceeds the conventional water level. Floods often threaten the safety of rivers, lakes and offshore areas, and even cause floods. Debris flow is a special torrent of mud, sand and stone formed in the valley under the excitation of rainstorm, water, snow and meltwater. Often manifested as a sudden outbreak, turbid liquid pushes forward and backward along the steep ravine, rushing down, the ground shakes and the valley vibrates. In a very short period of time, a large number of mud, sand and stones are washed out of ditches and piled up in a wide accumulation area, which often causes great harm to human life and property ... One incident after another, all kinds of disasters, are frightening, making us feel the importance of forecasting the weather.
We followed the staff uncle to the exhibition hall. As soon as we entered the exhibition hall, we saw some exhibition boards. Among them are the geographical and climatic characteristics of Huzhou, the relevant information about "agricultural gas", the achievements of Huzhou's meteorological cause in recent years and so on. I am most interested in the information about "agricultural gas": "agricultural gas" is the abbreviation of agricultural meteorology, and its function is to study the relationship between agriculture and meteorological conditions and its laws. It is not only a branch of applied meteorology, but also a basic subject of agronomy. Agriculture is mainly a production activity under natural conditions. A certain combination of light, heat, water and gas is beneficial to a certain production and forms effective agricultural natural resources; Another different combination is harmful to agricultural production and constitutes agricultural natural disasters. The basic task of agrometeorology is to study the temporal and spatial distribution law of these agricultural natural resources and agricultural natural disasters, to serve agricultural zoning and planning, rational distribution of crops, artificial adjustment of microclimate and cultivation management of crops, to carry out agrometeorological forecasting and information services, and to provide advice and suggestions for agricultural production, so as to make rational use of climatic resources, avoid unfavorable meteorological factors, take appropriate agricultural measures, promote agricultural high yield, reduce costs and improve economic benefits. How amazing! Predicting the weather can also be good for agriculture!
After that, we went into the video room and watched a video. This video shows the scientific and technological level of China meteorological industry and its meteorological achievements in recent years. The different characteristics and functions of geostationary observation satellites and non-geostationary observation satellites, as well as the functions of ground weather maps and high-altitude weather maps are also introduced. After watching the video, I was filled with emotion, only to know how shallow my meteorological knowledge is and how profound the meteorology of the motherland is!
After watching the video, we came to the control center of Huzhou Meteorological Observatory. There are many accurate meteorological instruments here, as well as electronic weather maps made by computers. Everything here makes me feel novel. My uncle and aunt are busy with their work. We were embarrassed to disturb them, so we looked at it for a while and then returned.
We walked around the building and came to the outdoor observation deck. There are many sophisticated meteorological observation instruments there. There are many instruments in the shutters, including dry-bulb thermometers exposed to the air and not directly irradiated by the sun, thermometers for measuring the temperature of wet bulb, which means that air in a certain state contacts the wet bulb in the wet-bulb thermometer, and adiabatic heat and moisture exchange occurs to make it reach saturation, and so on. There are all kinds of temperature measuring instruments on the ground, such as cement floor, asphalt floor, cement brick floor, etc ... You really have everything!
The interview is over, and our hearts are churning like sea water.
