摘要
该文选取2016年12月和2017年2月的4次转折性天气过程,利用气象观测资料对葫芦岛地区最低气温实况进行了统计分析,结果表明:冬季强降温与强升温均具有滞后性,在强降温后升温的第一天,或强升温后降温的第一天,地面最低气温并没有表现出明显的升温或降温,而是与前一天的最低气温相近,而在第二天,地面气温才开始随之大幅回升或下降。
In this paper,four transitory weather processes in December and February 2017 were selected,and theminimum temperature of the Huludao area was statistically analyzed using meteorological observation data.The re-sults show that strong cooling and strong warming in winter are lagging,the first day after warming up the tempera-ture,or strong temperature after the first day of cooling. The minimum temperature on the ground did not show signifi-cant warming or cooling,but the same day the minimum temperature is similar. On the next day,the surface tempera-ture began to pick up or fall sharply.
