正文(英文) | The U.S. rang in the new year with an unusually mild January 2021 that tied with 1923 for ninth-warmest January on record. Warmth was felt coast to coast with 48 contiguous states seeing above-average temperatures for the month. This winter’s mild temperatures also brought scant ice coverage to the Great Lakes in January, according to scientists at NOAA’s National Centers for Environmental Information. Here are more highlights from NOAA’s latest monthly U.S. climate report: Climate by the numbersJanuary 2021 temperature and precipitationThe average January temperature across the contiguous U.S. was 34.6 degrees F (4.5 degrees above the 20th-century average), which tied with 1923 for ninth-warmest January in the 127-year record. Above-average temperatures covered much of the West, northern and central Plains, Great Lakes and Northeast. North Dakota and South Dakota had their third- and fifth-warmest Januarys on record, respectively. January precipitation for the contiguous U.S. was 2.01 inches (0.30 of an inch below average), which placed the month among the driest third of the record. Below-average precipitation occurred across much of the Rockies, Northern Tier, Great Lakes, parts of the South and the Northeast. Meanwhile, portions of the West Coast, central and southern Plains, and parts of the Southeast had above-average precipitation. Great Lakes ice coverOnly 2.4% of the entire Great Lakes surface was covered by ice on January 24, the smallest amount of coverage on this date in the past 48 years. Peak ice coverage is expected to span only 30% of the surface sometime between mid-February and early March 2021. The amount of ice covering the Lakes during the peak is usually around 53%. ![]() A map of the United States plotted with significant climate events that occurred during January 2021.
