Why is it always windy in spring?

As we all know, wind is formed by air flow. In spring, the temperature gradually changes from cold to warm. Under the irradiation of the sun, the temperature of the cold earth keeps rising. The hot ground gradually heats the air near the ground, but the upper air is still cold, because the air can't directly absorb the heat of the sun. This has formed a "top-heavy" situation. The upper cold air drops, the lower warm air rises, and the air convection becomes stronger and stronger, forming a strong wind. Because the low pressure near the ground moves fast and the wind speed is high, spring becomes the season with high rowing power and the most frequent wind blowing.
