Rain Clouds Left by Typhoon Bavi Break 'Double High-Pressure' System

[Anchor]

The intensity of the heat wave has eased slightly due to the rain that fell overnight. This is because the rain clouds left by the 9th typhoon of the season, Bavi, pushed the North Pacific high-pressure system that had been covering the Korean Peninsula toward the south. A monsoon front is expected to form near this high-pressure system again.

Reporter Jeong Gu-hui has the details.

This is downtown Seoul after the heavy rain stopped.

Although the ground is wet and humid from the rain, relatively cool winds kept the daytime high temperature to just 26.2°C (79°F).

This is 5 degrees lower than yesterday, July 14.

[Shim Hyun-jung / Seongdong-gu, Seoul: It seems the heat has subsided a bit because of the heavy rain. The heat was suffocating, but it feels better now.]

As you can see, temperatures in most parts of the country, indicated in green, have dropped compared to yesterday.

However, this does not mean the heat wave has completely retreated.

Areas shown in yellow are actually hotter; the temperature in Miryang, South Gyeongsang Province, soared to 37°C (99°F) today from 32.8°C (91°F) yesterday, which is more than 10 degrees higher than in Seoul.

The cause of this large temperature difference is Typhoon Bavi.

As the rain clouds left by Bavi moved over the country, as shown here, they brought up to 135mm of rain to Seoul and lowered temperatures, mainly in the central regions.

However, these rain clouds did not just bring rain; they also pushed the North Pacific high-pressure system, which had been covering the Korean Peninsula in a double layer along with the Tibetan high-pressure system, toward the south.

Currently, this North Pacific high-pressure system has been pushed down to the vicinity of Jeju Island.

A monsoon front is expected to form along the edge of this North Pacific high-pressure system, and as a result, monsoon rain is forecast for Jeju Island and the Honam region tomorrow, July 17.

As the monsoon rain clouds move back north, they will bring rain to the Yeongnam and southern Chungcheong regions the day after tomorrow, Constitution Day, helping to cool down the heat slightly.

Until then, the heat wave in the Yeongnam region will continue.

Looking at the temperature forecast for Daegu:

It will remain hot tomorrow with temperatures rising to 35°C (95°F).

In the Seoul metropolitan area and Gangwon Province, monsoon rain is not expected until Saturday, July 18, so daytime heat exceeding 30°C (86°F) will continue starting tomorrow.
