How to learn weather science

Weather science is the study of the physical nature and laws of weather phenomena and weather processes, and used to produce weather forecasts, is an important branch of atmospheric science. Therefore, the research object of weather science is the whole earth's atmosphere, the research content is a variety of weather phenomena occurring in the atmosphere and its evolution. However, in practice, weather science is not to study all the physical processes of the atmosphere, but only to study the evolution of the weather plays an important role in those weather phenomena and weather processes.

The study of weather science has a history of more than a hundred years, its development with the innovation of means and technology, as well as with the development of the link, through four stages: in the 20th century before the 1920s, the main use of the ground, etc., to analyze a variety of barometric pressure systems and their weather distribution, which belongs to the first stage. 20 years later, due to the development of the success of the probe and the access to the high altitude meteorological data, so that the research of the ground expanded to the three-dimensional space. Expanded from the ground to the three-dimensional space, which is the second stage. In this stage, Norwegian meteorologists put forward the doctrine of polar front, Swedish meteorologists put forward the doctrine. The polar front doctrine outlines a typical polar front model (including the life history of a cyclone from inception, development to extinction), pointing out that in the temperate zones of mobility

There is a divergence between cold air from the poles and warm air from the tropics, which is known as a polar front (see). The theory of air masses states that weather changes at mid-latitudes are due to interactions from different sources. When an area is under the control of a certain air mass, a certain type of typical weather tends to occur. Where two types of air masses intermingle, weather changes tend to be very intense.After the 1930s, weather science entered its third phase. In 1939, Swedish meteorologists proposed the theory of long wave (planetary wave) by analyzing a large number of high-altitude weather maps, and found that polar cyclones develop in the specific position of the long wave, and the movement and development of the cyclone are closely related to the long wave. At this stage, weather science and power meteorology began to combine, in addition to the extensive application of Rossby's long wave formula, the British meteorologist R.C. Sutcliffe and the Norwegian meteorologist S. Peterson in the simplification of the vorticity equation (see) on the basis of the proposed judgment of the occurrence of the ground weather system, the development of the conditions, respectively. In addition, Finnish meteorologists have done a great deal of research on the characteristics of large-scale weather systems in the westerly wind belt, and American meteorologist C.W. Newton has done a great deal of research on strong convective storms. American meteorologist H. Riehl has made contributions to the analysis of tropical weather and the study of tropical atmospheric circulation and (see).After the 1960s, weather science entered its fourth phase. Due to the use of high-speed electronic computers, the combination of weather science and dynamical meteorology became closer. This was manifested in numerical simulation tests (see) and diagnostic analyses (see) of weather systems, which led to a further understanding of the physical mechanisms of the occurrence and development of weather systems. At the same time due to meteorological satellites provide a large number of sparsely populated areas (such as oceans, poles, plateaus and desert areas) of meteorological data, tropical meteorology and has been the rapid development of many new atmospheric movement phenomena are also constantly found. And then due to the continuous improvement of such means of detection, the study of, strong convective weather is also more in-depth.

Chinese meteorologists in 1925 first classified the types of weather in China; Shen Xiaohuang in 1931 on the cyclones in China's Jianghuai Basin made a study; Li Xianzhi in 1934~1936 period between the southern hemisphere and the northwestern Pacific Ocean, and initially proposed the interaction of the two hemispheres of the atmospheric circulation; Lu in 1943 to write the Chinese first book of Weather Forecasting, and studied the Chinese cold waves and typhoons in the 30s~40s; later, the study of the Chinese historical very heavy rainstorms, cold waves, plateau meteorology and the study of the high-altitude cut-off low pressure (see), the study of the interactions between the Chinese precipitation weather systems and the mid- and low-latitude circulations, and the study of and the tropical circulations, as well as the study of the air masses, fronts and so on by Zhu Binghai, have made their contribution to the weather science's development.
