Is the day long or the night long after the vernal equinox in 2022?
Whether the day is long or the night is long after the vernal equinox is often mentioned when people chat. As far as I know, the annual solar term of the vernal equinox is March 2 1, which is the fourth solar term in spring. On that day, the sun shone directly at the equator, and the northern hemisphere was divided equally day and night. After that, the days became longer and longer. It's good news for dogs who work overtime, at least they don't have to work overtime until 7 pm, and it will be dark outside the company.
Is the vernal equinox equal to day and night? The vernal equinox equals day and night.
Is the vernal equinox equal to day and night? It is a question that many people have at present. As far as I know, on the vernal equinox, the sun shines directly on the equator, and day and night are almost equal, that is, the time between day and night is equal, which is 12 hour. At this time, after half a year of darkness, the North Pole saw the sunshine for the first time on this day, and the corresponding South Pole will also bid farewell to the sunshine on this day. After the vernal equinox, the position of the direct sunlight point moves to the north, and the day time in the northern hemisphere becomes longer and the night time becomes shorter, but the difference is that the day time in the southern hemisphere becomes shorter and the night time becomes longer.
What's the change of day and night after the vernal equinox? The days are long and the nights are short after the vernal equinox.
Since the vernal equinox entered the spring, although its diurnal variation has been in doubt, people think that according to the data, the day and night of the vernal equinox are equally divided, but after the vernal equinox, it becomes a long day and a short night. The reason why this happens is that during the period from the vernal equinox to the autumnal equinox, the direct point of the sun is north of the equator, so the northern hemisphere is in a state of long days and short nights. With the increase of latitude, the days are longer; Even in the Arctic Circle, there are a few extreme days, but there are not many extreme days. However, there are also special circumstances. In the Arctic, the extreme day can last for about half a year. Because of symmetry, the situation in the southern hemisphere is just the opposite.
