Extreme heat and cold waves in North America Typhoons 9 and 10 approaching Japan may have an impact September 11, 17:48

The Japan Meteorological Agency's analysis revealed that the heat and cold waves that hit the Midwestern United States may have been affected by typhoons 9 and 10 that approached Japan this month.


The main reason is that the westerlies flowing in the northern hemisphere meandered due to the northward movement of the typhoon.

According to the Japan Meteorological Agency, the westerlies that blow eastward over latitudes 30 to 60 degrees north of the Northern Hemisphere were relatively straight at the end of last month, but since the beginning of this month they have begun to meander from north to south. It means that there is.



Regarding this, the Japan Meteorological Agency says that the westerlies may have been affected by typhoons 9 and 10 that moved northward on the west side of Kyushu from the 2nd to the 7th of this month and meandered.



There is cold air on the north side of the westerlies, warm air on the south side, and meandering north in the western part of the United States, so the area around the west coast of the United States is covered with warm air and remains hot and dry, and mountains. There are also many fires.



On the other hand, a westerly wind meandered to the south in the central part, and an unusual cold wave hit Colorado, and the maximum temperature was 38 degrees on the 5th of this month, but the minimum temperature reached 0.6 degrees below freezing on the 8th, three days later. It's getting cold rapidly.



According to the Japan Meteorological Agency, "a strong typhoon is a phenomenon that occurs occasionally when it passes near Japan, but the meandering is gradually disappearing."
