Globe for observing vernal equinox and solar terms

It can be seen from the schematic diagram of the earth's revolution that when the earth is in position A, the latitude of direct sunlight is the equator, which is vernal equinox in the northern hemisphere, and the date is around March 2 1; When the earth is in position B, the sun shines directly on the tropic of cancer, which is the summer solstice in the northern hemisphere, and the date is around June 22; When the earth is in the third position, the latitude of direct sunlight is the equator, which is the autumn equinox in the northern hemisphere, and the date is around September 23; When the earth is in position D, the latitude of direct sunlight is tropic of Capricorn, which is the winter solstice in the northern hemisphere, with a date of about 65438+February 22nd.

As can be seen from the figure 1, the direct point of the sun is the tropic of Capricorn, and when the sun directly hits the tropic of Capricorn, it is the winter solstice in the northern hemisphere. Therefore, the extreme night phenomenon should occur in the northern part of Norway, Sweden and Finland, which are crossed by the Arctic Circle.
