This... spring seems to have no origin, nature created spring!
But here are some introductions to spring, you can refer to them.
Spring is one of the four seasons of temperate zones, the transition from winter into summer. Astronomically, some Western countries consider spring to begin with the vernal equinox (around March 20 in the Northern Hemisphere, and September 23 in the Southern Hemisphere), and ends with the summer solstice (around June 21 in the Northern Hemisphere and December 21 in the Southern Hemisphere). Such conventions are by no means universal, however. In Chinese astronomy, for example, the vernal equinox instead marks the middle of spring, which begins around the time of Lichun (around February 4). In the Irish Calendar it is counted as the whole months of February, March and April. In meteorology, it is (also by convention) instead counted as the whole months of March, April , and May in the Northern Hemisphere and September, October, and November in the Southern Hemisphere. For many people in temperate parts of the United States, spring is synonomous with baseball, either Major League Baseball's Spring Training or time to sign up for Little League Baseball.
As in summer, the axial tilt of the Earth is toward the Sun, and daylight hours are greater than or equal to 12 hours and rapidly increasing (especially in higher latitudes). The hemisphere begins to warm significantly, causing new plant growth to spring forth, giving the season its name (see Effect of sun angle on climate). Snow (if any) begins to melt, and rivers and streams swell with runoff and spring rains. Most flowering plants bloom this time of year, in a long succession beginning even when snow is still on the ground, and continuing into early summer. In normally snowless areas, "spring" may begin as early as February during warmer years, with subtropical areas having very subtle differences, and tropical ones none at all. Subarctic areas may not see "spring" at all until May or even June, or December in the outer Antarctic.
