March begins in the grip of winter. Its turning point is the Vernal Equinox (March 19–21), when the subsolar point crosses the equator northward, granting nearly equal day and night. However, meteorologically, March is a month of extreme gradients. In the Northern Hemisphere, the jet stream begins its erratic northward retreat, causing violent collisions between Arctic air and rising warm Gulf air. This produces the “false spring” phenomenon—a week of 20°C warmth followed by a blizzard. month of spring

By May, the Northern Hemisphere’s landmasses have fully warmed. The jet stream settles north of 45° latitude. Day length increases rapidly—at 45°N, May gains nearly 15 minutes of daylight every week. Frost dates pass for most temperate zones. May is statistically the driest spring month in many regions (e.g., Mediterranean climates), but also the month of maximum plant transpiration. | Feature | March | April | May
