Weather of Arabia - The winter season is characterized by its cold and a lot of rain and snow, as well as short daylight hours and long night hours, but is there a fixed date for the beginning of winter? And when does winter start this year 2022?
In fact, there are two separate dates that can be said to represent the beginning of winter, one of which is based on the astronomical start of the seasons, and the second is a fixed date that meteorologists use to determine the beginnings of the seasons, but it is not the official start.
The winter season begins astronomically on the day of the winter solstice, and the date of the winter solstice in the northern hemisphere comes in the month of December, and in the southern hemisphere it comes in the month of June, and the winter season extends until the day of the spring equinox.
The beginning of the winter season is astronomically the official beginning of it, and the astronomical beginning of the seasons determines the tilt of the Earth’s axis as it revolves around the sun, which leads to the two halves of the Earth receiving a different amount of solar radiation, so that either half of the Earth tilts towards the sun and the season is summer or it tends away from the sun And the season is winter.
This year, the winter season begins on Thursday (December 22, 2022) and ends on Tuesday (March 21, 2023), so that it lasts 89 days.

Meteorological seasons are derived by dividing the year into four periods, each spanning three months. These seasons are divided to coincide with the beginning of the months, which facilitates the process of monitoring and forecasting and comparing seasonal and monthly statistics.
According to the meteorological calendar, the first day of winter is always December 1 and ends on February 30, meaning that the winter season in meteorology extends for 3 months: December, January and February.
With the entry of the northern part of the globe astronomically in the winter, the square period begins, which is the coldest during the year. Winter is on very cold nights when the sky is clear.
The chances of torrential rains and landslides and rockslides also increase during the winter season compared to the rest of the year, especially when the surface of the earth is saturated with rain water.
