2003年11月 Saint Cloud 天气 Summary

不管是湿的还是白的，还是太干了

     November continued the trend of below normal 降水 that began on July 15. 的 total melted 降水 officially recorded in Saint Cloud was 1.05 inch, nearly half-an-inch below normal. 的 rainfall was measured at the Saint Cloud Regional Airport, but the snowfall was melted 和 recorded at the Math-Science Building at Saint 澳门威尼斯人娱乐城. 的 low 降水 has allowed the 降水 deficit since July 15 to reach nearly 6英寸 (see 2003年秋季统计数字). 的 最终周降水报告 from the 明尼苏达州 Climatologist's Office shows that all of Minnesota, except for a swath from Alex和ria 和 Glenwood through Little Falls, Milaca, 和欣克利, had below normal rainfall for the growing season. 的 最新旱情监测 from the National Drought Mitigation Center shows that most of central Minnesota is listed as having a 适度的干旱. 然而, extreme drought conditions cover the area approximately bounded by the Twin Cities Metropolitan Area, 密西西比河, 和I-35.

     Much of the November 降水 fell in the form of snow. 的 Saint Cloud November snowfall totalled 13.2 inches, nearly four 和 a half inches above normal. 的 bulk of the snow fell on 11月3日, when 3.8 inches of wet snow fell, breaking a daily snowfall record, 和 on 11月23日, when 7.3 inches fell, tying a snowfall record. 11月22日至23日的降雪 was the larrgest in central Minnesota with Little Falls 和 Wadena recording 10 inches of snow. 的 2003年11月 snowfall ranks as the 16th heaviest November total snowfall in the 96 years of Saint Cloud snowfall records. 然而, high November snowfalls have been the rule over the past 10 years. Higher November snowfalls occured in 1996 (13.4 inches; 15th place), 1993 (13.5 inches; 14th place), 1992 (14.1 inches; 13th place), 和 1991 (21.3 inches; 4th place). 的 snowiest November on record was 1940 (26.9 inches), which included the Armistice Day blizzard. (Ten snowiest/driest Novembers are here.)

    November's 温度s were within a degree of normal. As was the case the past couple of months, the near-normal average 温度 was the result of some very warm weather 和 some very cold weather. 的 warmer weather in the middle of November produced some near record highs in the 50's. 每次降雪后, 天气变冷了, including Saint Cloud's first sub-zero low of the season on 11月24日. 在我们最近一连串的暖冬中, there have been only two other Novembers since 1997 with a sub-zero low (1997, 2000). 然而, sub-zero lows in November have been a fairly regular occurrence; there were 9 November days with a sub-zero low during 1994-1996. (这里是历史上零下的低点)

    11月30日是结束日 气象下降. 2003年秋季 was dominated by the dry weather with rainfall half an inch below normal. 的 average 温度 ended up a bit more than a degree above normal. 通常, the fall is the best season to try make up a deficit since usage by plants is at a low level after the growing season ends. It is possible that the current snowpack could melt, allowing some rain to penetrate the soil before it freezes, but it is more likely that we will have to make up that deficit after the ground thaws during the spring. (这里是2003年秋季的统计数据.)

   Finally, Saint Cloud has a "new" normal snowfall. 的 National Climatic Data Center issues new 30-Year normal 温度s 和 降水 statistics at the end of each decade. Currently, the 30-year period are the years 1971-2000. (My site is the only free on-line source of Saint Cloud's 30-year daily normal 温度s 和 降水 以及每月的正常 温度 和 降水). 然而, the NCDC has discontinued keeping snowfall records. 因此，我重新计算了 30-year-normal降雪 (1974-2003)度过了最后一个寒冷季节. 尽管最近几个冬天没有下雪, the heavy snowfalls during most of the past 30 years pushed the normal snowfall to 46.8英寸，上升1英寸.2 inches from the 1961-1990 values 和 more than 5 inches higher than the historic Saint Cloud average of 41.6英寸.
