Spring Begins March 20, Temperatures Rise in U.S.

Spring officially begins at 5:01 am on March 20, with temperatures expected to reach the 60s and evening showers in Baltimore. The season will last until June 20, during which average high temperatures will rise from 56°F to 86°F, and daylight will increase from 12 hours to nearly 16 hours by the season's end. This marks a transition from winter to warmer months, as spring is characterized by blooming flowers and longer days. Additionally, East Asia experiences a significant climate phenomenon known as 'spring persistent rainfall' (SPR), which accounts for over 35% of the region's annual rainfall, a contrast to North America's lack of a distinct rainy season. A study has traced the evolution of SPR, highlighting the influence of paleogeography and climate change on rainfall patterns over millions of years. The findings emphasize the geological factors that contribute to the differing rainfall experiences between these regions.
