Weather of Arabia - With the onset of spring, we begin to notice distinctive natural manifestations, the most important of which are the opening of flowers and the blossoming of trees after their leaves fell during the fall and winter, as the chances of rain decrease and the presence of clouds decreases, which means that a greater amount of sunlight reaches the surface of the earth and plants, which stimulates the growth of plants and tree leaves. But is there a specific date for the start of the spring semester? And when does the spring semester start this year 2023?

Countdown to days</a><h3 style=";text-align:left;direction:ltr"> When does the spring semester start this year 2023?</h3> For meteorology, spring begins on a fixed date every year, which is (1) March, which is the unofficial start of spring determined by weather patterns, while the official start of spring this year will be on Tuesday, March 21 2023 .

On this day, the earth is in an upright position with respect to the sun, so the earth’s axis is not inclined towards the sun or away from it, so day and night are equal in all countries, and after this day the sun’s rays begin to head north of the equator, until it reaches its northernmost point on the day of the summer solstice. <img alt="" src="https://s7d2.scene7.com/is/image/TWCNews/0528_ky_meteorological_seasons" style="width: 609px; height: 342px;" /><h3 style=";text-align:left;direction:ltr"> What is the difference between the beginning of spring astronomically and in meteorology?</h3><ul style=";text-align:left;direction:ltr"><li style=";text-align:left;direction:ltr"> Astronomically: The beginning of spring astronomically depends on the movement of the earth around the sun, which changes with it the amount of solar energy that parts of the earth receive, and thus the weather patterns differ.</li><li style=";text-align:left;direction:ltr"> In meteorology: As for the beginning of the spring season in meteorology, it is determined based on the annual temperature cycle and weather patterns. Meteorologists and climatologists divide the seasons into groups of three months each, based on the similarity in temperatures, and the spring season in meteorology includes the three months: March - April - and May, because temperatures The temperature is almost the same, and changes regularly during those months.</li></ul><h3 style=";text-align:left;direction:ltr"> Why are different dates for the beginning of seasons determined in meteorology?</h3> Determining dates for the four seasons in meteorology was due to the difference in length from 89 to 93 days in the duration of the astronomical seasons, and it was difficult for experts to compare statistics from one year to another, and weather science and meteorology remain important in studying the beginnings of the seasons depending on the average temperatures This is due to its proximity to what is actually happening on the ground, and this is of great importance to various sectors such as the agricultural sector, the industrial sector, and others.<h2 style=";text-align:left;direction:ltr"> Facts about the vernal equinox</h2> In the following, we will learn about facts about the day of the vernal equinox that make it a special day from the rest of the year:<ul style=";text-align:left;direction:ltr"><li style=";text-align:left;direction:ltr"> The spring season begins astronomically and officially on the day of the spring equinox in one hemisphere, while the autumn season begins astronomically and officially in the other hemisphere.</li><li style=";text-align:left;direction:ltr"> Spring lasts about 92 days, from the vernal equinox to the summer solstice.</li><li style=";text-align:left;direction:ltr"> On the day of the equinox, the sun in its apparent journey on the horizon perpendicular to the Earth's equator.</li><li style=";text-align:left;direction:ltr"> Day and night are equal all over the world on the day of the equinox.</li><li style=";text-align:left;direction:ltr"> The dividing line between day and night on the globe passes through the north and south poles of the earth.</li><li style=";text-align:left;direction:ltr"> The day of the equinox is an opportunity to determine directions precisely because the sun rises in true east (at an angle of 90 degrees with the horizon), and sets in true west (at an angle of 270 degrees with the horizon).</li><li style=";text-align:left;direction:ltr"> The sun sets on the vernal equinox in March for the first time at the South Pole after a 6-month day.</li><li style=";text-align:left;direction:ltr"> On the vernal equinox in March, the sun rises for the first time at the North Pole after a 6-month night.</li><li style=";text-align:left;direction:ltr"> The vernal equinox does not necessarily mean the onset of warm weather or rapid changes in weather.</li></ul> Also read: <a href="https://www.arabiaweather.com/ar/content/%D8%A8%D8%A7%D9%84%D8%B5%D9%88%... | The most wonderful colors of spring in some countries of the Middle East</a>
