When are the four seasons in 2022?

Introduction: The changes of the four seasons bring changes to our lives, and we can also see the beautiful scenery of each season and feel the difference of weather and temperature in each season. Every year the four seasons are in samsara, so do you know when the four seasons in 2022 are? How many months are there in spring, summer, autumn and winter in 2022? The following is the content carefully prepared by Bian Xiao, hoping to help everyone!

When are the four seasons in 2022?

The spring of 2022 is from February to May, and the specific time is from February 4 to May 5.

The summer of 2022 is from May to August, but the climate in different places is different due to the great difference between the north and the south of China, so the specific area depends on your location. Summer is the second season of the year, and the high temperature in summer in the northern hemisphere is the most remarkable climate feature. Because of the different regions and dry and wet environments, it will produce a dry and hot or humid and rainy climate. The summer of 2022 starts from the long summer on May 5th and ends in beginning of autumn on August 6th, but this does not mean that the temperature will drop after beginning of autumn.

The autumn of 2022 is from August to 165438+ 10, and the specific time is August 7-165438+ 10.

Autumn can be said to be one of the favorite seasons of the year. Autumn is the season of harvest, but also the season of mature seeds. There are flowers in autumn, and the weather is quite mild, not as cold as winter, not as inflammatory as summer. You think that autumn has so many benefits, who can not like it? Although autumn is also the season when flowers fall and blinds fall, it is a seasonal cycle, not to mention it will recover after winter.

The winter of 2022 will be 165438+ 10 to February, and the specific time will be 165438+ 10/0/7 to 3 February.

How many months are there in spring, summer, autumn and winter in 2022?

In 2022, spring, summer, autumn and winter are March, April and May, summer is June, July and August, autumn is September, 10/1, winter is 12,1,and February. This is divided according to the temperature. By month, spring is 1.2 and March, summer is April, May and June, autumn is July, August and September, and winter is 10/1and 65438+February.

From vernal equinox to summer solstice to autumnal equinox, the northern hemisphere is in summer and the southern hemisphere is in winter. During this period, the northern hemisphere has long days and short nights, while the southern hemisphere has short days and long nights. The north pole is in the extreme day and the south pole is in the extreme night; The height of the sun north of the Tropic of Cancer is always greater than the average, while the height of the sun south of the Tropic of Cancer is less than the average.

North of the Tropic of Cancer, the sun rises on the northeast horizon and sets on the northwest horizon. On the vernal equinox, the sun all over the world rises in the east and sets in the west. From the autumnal equinox to the winter solstice and then to the vernal equinox, the northern hemisphere is in the winter half year and the southern hemisphere is in the summer half year.

During this period, the length of day and night, the extreme value of day and night and the height of the sun in the northern and southern hemispheres are contrary to the above situation. North of the Tropic of Cancer, the sun rises from the horizon in the southeast and sets on the horizon in the southwest. The northern hemisphere turns from summer to winter and the southern hemisphere turns from winter to summer.

During this period, the days in the northern hemisphere are getting shorter and shorter, the nights are getting longer and longer, and the extreme day area is getting smaller and smaller. In the southern hemisphere, the days are getting longer and longer, the nights are getting shorter and shorter, and the polar night zone is getting smaller and smaller. The height of the sun has been declining in the north of the Tropic of Cancer and rising in the south. North of the Tropic of Cancer, the rising direction of the sun changes from northeast to southeast, and the setting direction changes from northwest to southwest. The autumnal equinox rises due east and lands due west.

The causes of the formation of the four seasons

With the rotation and revolution of the earth, the equatorial plane and the ecliptic plane form an included angle of 23 26'. Because of the declination angle, the direct point of the sun moves back and forth between 23 26' in the north and south latitudes. On the earth, except the equator, the length of day and night at the same latitude and the height of the noon sun change with the seasons in a year, which leads to the regular changes of solar radiation at the same latitude with the seasons, thus forming four seasons.

From the astronomical point of view, summer is the season with the longest day and the highest sun height in a year, and it is also the season with the most solar radiation. Winter is the season with the shortest day and the lowest sun height in a year, and it is also the season with the least solar radiation. Spring and autumn is the transitional season between winter and summer, and the solar radiation is in the middle.
