One of the twenty-four solar terms, the "Summer Solstice", is here.

The summer solstice is the most northerly day of the year in the year, the

extreme of the sun's northward travel, and the longest day in the northern

hemisphere and the region north of the Tropic of Cancer. The higher the

latitude, the longer the day. This is because the "day-long-night-short effect"

caused by the tilt of the Earth's rotation axis, the closer it is to the two levels,

the more obvious it is.

After the summer solstice, although the point of direct sunlight begins to

gradually move southward from the Tropic of Cancer, and the days in the northern

hemisphere begin to gradually shorten, the heat radiated to the ground by the sun

is still more than that of the ground to the air, so in the following period, the

temperature will decrease. Continue to rise, so there is a saying that "the summer

solstice is not too hot".

After the summer solstice, the ground is heated strongly, the air convection

is strong, and thunderstorms are easy to form. This kind of hot thunderstorms

come and go quickly, and the rainfall range is small. There may be rainstorms in

some areas, which are prone to flood disasters. Attention should be paid to

strengthening flood control work. The editor also reminds everyone to bring rain

gear when going out!
