-
Jeongeup, North Jeolla Province, at 5:50 p.m.
500 hPa
-
The isometric lines are very winding.
-
Since our country is located on the east side of the trough, ground low pressure will develop due to convergence.
-
Considering the time of the hailstorm at 5:50 p.m., we can expect that the cut-off low with the cod core will move toward the Korean Peninsula.
-
The temperature is about -20 degrees Celsius.
850 hPa
-
The temperature is about seven degrees Celsius.
-
It is baroclinic, so because of the strong advection, wet air is introduced.
-
A large temperature difference with 500 hPa is about 27 degrees, which causes instability at the upper and lower level.
Surface
-
It is predicted that this case can be classified as an front type since there are some cold fronts at surface.
-
As hailstones pass, the front can also be seen moving southeast of the Korean Peninsula.
