What are the characteristics of summer?
Features: Summer is the second season of the year and one of the four seasons. In most areas, summer is a hot season with possible water shortages. In addition, since most students in the northern hemisphere are on summer vacation during summer, it is also a very busy tourist season.
In the northern temperate zone, the meteorologically significant summer is from May 21st (Xiaoman) to August 22nd (end of summer heat); in the southern temperate zone, the meteorologically significant summer is November 21st (light snow in the northern hemisphere) ~February 18 of the following year (rain in the northern hemisphere).
Westerners generally call the summer solstice and autumn equinox summer. In the Southern Hemisphere, December, January and February are generally designated as summer. In a climatological sense: when the average temperature for five consecutive days exceeds 22 degrees, it is considered summer, and when the average temperature for five days is below 22 degrees, it is considered autumn.
