February 10 is the International Meteorological Festival every year. 1991February 10, a place near Paris, France, called Isi? The first International Meteorological Festival was held in Remorino.

Meteorological knowledge

? It is raining, isn't it? Hook cloud is actually the first cloud in the weather system, so once it appears in the sky, it means that the weather system is approaching this place and it is going to rain.

? Swallows flying low in the snake aisle, is it raining heavily? Before it rains heavily in summer, the air pressure will generally decrease, but small animals such as swallows and snakes are very sensitive to the air pressure decrease and will fly around, which means it will rain heavily.

So why not just say that there is no rain, relative humidity and precipitation probability in a certain area? Let's look at the relative humidity first. Relative humidity is a new mass forecast project launched by the Meteorological Observatory in recent years, which refers to the saturation of water vapor in the air and has a great relationship with people's health. If the relative humidity is high, such as 100%, then you will feel bored. And say? Local? It is because the scientific level is not very high now. For some forecasting projects, especially severe weather, the forecasting level is not very high. It stands to reason that with the progress of science and technology, we think it will gradually improve its own forecasting level and may use the word local less.

There are also many weather indicators, which are signs of strong winds in TV weather forecast. One section is the second wind, and the third section is the sixth wind. Therefore, in meteorology, the average wind speed is greater than or equal to level 6, which is called gale, so it is a sign of gale. Speaking of climate, China has many extreme climates. June, 2002, 5438+ 10 was the warmest winter since the founding of New China, and the national average temperature was the highest in the same period in recent 40 years. In February+February, 65438, there was a week-long snowfall in northwest, north China and Huanghuai areas, which is also rare in history, such as Xinjiang, Inner Mongolia, most parts of Shanxi, northern Shaanxi and Beijing.

The first reason is that China's temperature changes periodically, once every 30 years. Before 1920, it was a cold cycle, 1920 to 1940 was a warm cycle, and it was a cold cycle in 1950s and 1970s. After the 1980 s, it entered the warm period cycle. So now we are in a warm cycle.

The second reason is that since the industrial age, carbon dioxide has been discharged into the atmosphere in large quantities, so its influence on temperature is increasing. From a global perspective, since the 1980s, the rising trend of global temperature has continued. Moreover, this precipitation is indeed the longest snowfall in Beijing since June+February 1875 in 438, breaking the historical record. Not only does the snowfall in Beijing, Shanxi and Hebei exceed the historical record, but also extreme weather and climate events are prone to occur in this warming environment. This is an event and should be normal and reasonable.
