Busan experienced largest temperature difference ever in January

Busan experienced the largest temperature difference ever in January, with a temperature difference of over 20 degrees between the highest day and the lowest day.

According to the results of last month’s climate analysis announced by the Korea Meteorological Administration, the national average temperature last month was -0.6’C, similar to the normal January temperature (-0.9’C).

The middle of last month was unusually warm and the second half was record cold.

Last month, the warmest day was on the 13th with an average temperature of 9.6’C and the coldest day was the 25th with an average temperature of -10.2’C.

The average temperature difference between the two days was 19.8’C, the largest among January temperature differences since 1973, which is the basis for meteorological records.

The same goes for Busan, Ulsan, and Gyeongnam.

According to the Busan Meteorological Administration, the average temperature of Booul-gyeong last month was 1.7’C, which was similar to the January temperature of 1.5’C but the temperature difference was the largest in January.

The temperature difference between the warmest day — 13.4’C on the 13th and the coldest day -7.3’C on the 25th — reached a whopping 20.7’C.

The reason why the middle of the year was warm is that a migratory high pressure was located in the southeast of Korea and a warm southwest wind was strongly introduced as the low pressure was accompanied by a low pressure at the edge of the high pressure.

It was cold in the latter part of the month because the Ural Mountains developed a pressure ridge, and cold air from the north poured into East Asia. In the North Pole, the ‘negative Arctic Oscillation’ condition continued, where the air currents surrounding the North Pole were weak.

Last month, the nationwide precipitation was 40.5 mm, more than the average year (17.4-26.8 mm).

The average precipitation in Buul-gyeong was 63 mm, far exceeding the normal year (17.8-34.3 mm).

This is because the southwest wind blowing between the migrating high pressure and the low pressure passing through the central region was not only warm, but also contained a lot of water vapor.

On the 13th of last month, 108.9 mm of rain fell in Geoje City, Gyeongnam Province, which is very unusual for January.

Since 1973, there have been only two occasions, including this time, when it rained more than 100mm in one day in January at 62 observation points. Previously, on January 27, 2020, 113.6 mm fell in Ulsan.
