未來的天气怎么样,这是人們一直关心的問題。農業生產在很大的程度上受天气变化的影响。天气对于工業生產也有一定的关系。長时期以來,劳动人民一直在探索着各种天气变化的規律,他們累積了很多的經驗。但是对天气的变化作科学的观測还是近代的事。現在人类已經可以預报未來几天內的天气变化了。天气怎么样來預报呢?这就得掌握天气情况,掌握它的發展規律。天气的变化是由于空气中冷和热的矛盾的对立、斗爭造成的;由于冷热分布不匀,空气中就產生了气流,也造成了水汽的蒸發、凝結(云、霧……),而水汽的蒸發和凝結又反过來影响空气中冷和热的分布,影响气流。困难的是,这种冷热、干湿和空气运动的情况,我們还知道得
How is the weather in the future? This is a problem people have always been concerned about. Agricultural production is affected to a large extent by weather changes. The weather also has a certain relationship with industrial production. For a long period of time, the working people have been exploring the laws of various weather changes, and they have accumulated a lot of experience. However, scientific observation of weather changes is a modern matter. Now humans can already predict weather changes in the next few days. How do you forecast the weather? It is necessary to grasp the weather conditions and master its development rules. The change in weather is caused by the contradiction and struggle between the cold and the heat in the air. Due to the uneven distribution of heat and cold, air is generated in the air, and the evaporation and condensation of water vapor (clouds, fog, etc.) are also caused. The evaporation and condensation of water vapor in turn affect the distribution of cold and heat in the air, affecting the air flow. The difficulty is that we also know about this kind of hot and cold, dry and wet and air movement.
