What is the solar altitude angle and direct latitude at the vernal equinox?

1, at the vernal equinox, when the sun is directly at the equator 0, the solar altitude angle in Beijing at noon that day = 90-| 40-0 | = 50.

In this solar term, the direct point of the sun is on the equator, which is divided equally between day and night. As we all know, the length of day and night is the same only on the equator for a whole year. At the vernal equinox, we can see this phenomenon in the northern hemisphere. After that, the direct point of the sun will continue to move northward, and the days will be longer and the nights will be shorter, so the vernal equinox is also called the rising equinox. As for other latitudes with direct sunlight, you can also refer to them. The summer solstice is in the Tropic of Cancer, the winter solstice is in the Tropic of Cancer, and the autumnal equinox is also at the equator.
