In which country did the conventional weather forecast system originate?

Formal weather forecasting system originated in Britain.

185 1 year, the observation data were transmitted by telegraph for the first time in Britain, and the ground weather map was drawn, and the weather forecast was made according to the weather map. Since the 1920s, air mass theory and polar front theory have been applied to weather forecast.

In 1930s, the invention of radiosonde, the appearance of high-altitude weather map and the wide application of long-wave theory in weather forecast made the analysis of weather evolution develop from two-dimensional to three-dimensional. In the late 1940s, the application of weather radar provided an effective tool for forecasting precipitation, typhoon, rainstorm and severe storm.

Animal weather forecast

1, Swallow: It's sultry, and flocks of swallows are flying around against the ground, which is a sign of strong wind and heavy rain. Because the air humidity is high before it rains, the wings of insects are wet and can't fly high. To catch insects, swallows fly low for food.

2. Bees: Going out early and returning late when picking honey indicates that it will be fine the next day; If it stays in the nest for a long time, or leaves late and comes back early, it will rain in the near future; If it picks honey in the drizzle, it indicates that it will clear up.

3. Ants: If you have white seeds in your mouth, line up in a long queue and move to the heights in a hurry, it indicates that there will be continuous rainy days and heavy rainfall; If you move to a lower place, tell us: there will be drought in the future, and there is not enough water here.

4. Misgurnus anguillicaudatus: Misgurnus anguillicaudatus is called a "living barometer". If the loach is fidgety, churning up and down, and many bubbles appear on the water surface, it means that it will rain soon, or the north wind will blow; On the contrary, the loach perches quietly on the bottom of the water, indicating that the weather is fine.

5. Snake: The snake comes out of the hole, walks sideways on the road, or crawls slowly in one direction, indicating that it is going to rain. If the number of snakes coming out of the hole increases, it means heavy rain; On the contrary, there is less rain.
