As can be seen from the following figures, the February temperature in Manitoba has generally maintained a pattern of being higher in the south and lower in the north over 109 years. Upon closer examination of February 2023, unusually low temperatures were observed in the northeastern region, a situation not seen in many years.
For the calculation of the February temperature's time trend, we have also divided it into three periods. In the first period from 1915 to 1964, there is absolutely no time trend that reaches a significant level. In the other two periods, although there are regions with warming that passes the significance level, the warming areas between the two periods do not overlap, and their warming magnitude and range are both smaller than in January.
