2018年1月圣克劳德天气摘要


强烈的寒冷被温暖的时期所平衡

January 2018 St. Cloud Weather Summary

气象冬季的第二个月出现了寒流, 但结果比平均温度要高一些. The average St. Cloud January temperature was 13.3°F, 1.7°F milder than average. 在1月的前两周,有6天的气温比平均水平低至少13度. However, 在1月的最后两周,只有两天的气温没有高于平均水平.

寒冷的时间段包括16个早晨 low temperature of zero or colder, right about average for January. 在截至2月2日的冬季,有26个早晨的最低气温为零度或更低. 整个冬天的平均气温是43天. 有一天早晨最低气温至少是零下20度, -22 degrees on January 6. 这样看来,今年冬天还有两个早晨,还远远不够 5 days in an average winter. On January 5在美国,气温从未超过零度,这使它成为 今年冬天的第五天,气温从未低于零度 哪个比4稍高.整个冬季平均3天.

St. 在12月24日至1月6日期间,连续13个早晨的最低气温为零度或更低. 上一次连续至少13次达到零度或更低的低点是2003年2月4日至16日. 在1996年1月18日至2月6日期间,连续20天的时间更长. 其中包括连续6天最低至少为-30,最后一天为6月30日. Cloud hit -40 (February 2, 1996, 当天塔创下了明尼苏达州零下60度的低温记录). The St. 连续零度或零度以下的最低云量记录是37天, 故事发生在1936年1月17日至2月22日之间.

However, there were no cold record temperatures set or even approached. In fact, 1月份创下的唯一气温记录是创纪录的32度的低温, set on January 10.

上个月最不寻常的是明尼苏达州中部持续缺雪. The St. Cloud Prison only recorded 4.6 inches of snow in January. This was 4.比一月份的平均气温低8英寸.6 inches. For the winter season so far, St. Cloud has only picked up 16.4 inches, 10.8 inches below average. In recent years, the winter of 2011-2012 also had 16.2 inches through the end of January. 最近,最少量的圣. 2006-2007年1月的云雪只有4次.7 inches of snow. However, 自1905年以来,有41个冬天的降雨量低于1月底的17英寸, 因此,起步如此缓慢并不罕见.

本月最大的一场降雪发生在圣保罗. Cloud was not the January 22 blizzard that hit the Twin Cities, southwestern, south central, 以及明尼苏达州中东部,降雪量达8-14英寸. However, the St. 云区没有任何积累. The largest snowfall was the 3.1月14日的降雪达到了4英寸. This actually set a new daily snowfall record for St. Cloud, since the old record was 3.0 inches, set in 1952. 值得注意的是,到目前为止,近一半的季节性降雪是在2天内产生的, January 14 and November 4, which also produced a record daily snowfall of 4.0 inches.

The snow cover disappeared in St. 1月27日,连续47天有云,地面至少有一英寸. 整个冬天,有50天地面上至少有一英寸积雪. 因为我们已经到2月2日没有任何积雪覆盖, 我们不太可能超过连续47天的纪录. 平均连续86天,平均总积雪日数为101天.

降雪中液态水的含量也远低于1月份的平均水平. St. Cloud only received 0.18 inch, 0.47 inch below average.

冷暖交替的原因有两个方面. 首先,风向偶尔会发生变化. 它们是在寒冷时期从加拿大中北部来的, 虽然有几个时期有更多的西向东风向, 它们带来了从落基山脉东坡降下来的温和空气. At other times, 加拿大中北部最冷的空气流入美国和加拿大东南部,暂时耗尽了最冷的空气供应. Then, 在格陵兰岛的空气准备好向南移动之前,其他风向不得不将更多的格陵兰空气推向加拿大中北部. 这使得即使是加拿大中北部也有一周没有真正的冷空气.

我们肯定是在更冷的周期中开始二月, 但考虑到现在加拿大寒冷的空气量, St. 云可能只是被北极的空气擦了一下就飞走了, 所以我们可能不会像圣诞节和新年周末那么冷.
