This month of April is marked by particularly pronounced and repeated variations. Last week, temperatures dropped from near normal to summer levels over the weekend.
At the start of the current week, they fell significantly. This reduction is only temporary. They will once again display summer values this weekend, before dipping again next week. The strong fluctuations in the thermometer are, among other things, the result of variations in the altitude current. The warm air coming from Africa has an increasingly higher temperature. Temperatures can then be summery earlier and earlier in the year. But when the dominant air mass returns from the Arctic, the difference is even more abrupt and significant, increasing the yo-yo effect. The website of meteorologist Guillaume Séchet finally emphasizes a problem generated by current climate change. It accentuates the contrasts. It can be seen in this animation provided by The Weather Channel of the coming days. It shows the temperature of the Azores anticyclone, as well as the origin of the air mass which dominates in France.
