1. Temperature Analysis
Daily Temperature
2024.08.01
High and humid air inflow due to the prevailing southwest wind
High-temperature and humid air accumulates as radiant heat due to weak wind speed
Maximum temperature : 33.2℃
Minimum temperature : 27.3℃
2024.08.03
Hot and humid air inflow through warm advection
Low wind strength causes air to stay and accumulate
Maximum temperature: 34.2℃
minimum temperature: 27.2℃
2024.08.05
Weak circulation still exists over the Korean Peninsula, high possibility of high-temperature air staying
Heat waves are likely to persist due to accumulated radiant heat due to unclear air flow
Maximum temperature: 33.7℃
minimum temperature: 26.9℃
2024.08.02
High and humid air inflow due to the prevailing southwest wind
The flow over the Korean Peninsula is slow due to weak winds, and high-temperature air accumulates as radiant heat
Maximum temperature : 32.5℃
Minimum temperature : 28.2℃
2024.08.04
Circulation flow over the Korean Peninsula is weak, hot air is likely to stay and air flow is not clear
The heat wave is expected to continue due to the accumulation of radiant heat
Maximum temperature: 36.2℃
minimum temperature: 27.3℃
2024.08.06
Overall, atmospheric stability conditions are being formed where wind speed is weak and radiant heat can be accumulated
Heatwave is likely to persist
Maximum temperature: 33.5℃
minimum temperature: 25.6℃
2024.08.07
Weak circulation flow still exists over the Korean Peninsula, high possibility of hot air staying
Due to the lack of clear air flow, radiant heat is accumulated and heat waves are likely to persist
Maximum temperature: 33.4℃
minimum temperature: 27.2℃
Changes in surface temperature and precipitation
-
The surface temperature (red line) shows repeated rise and fall throughout the day, a natural pattern in which the temperature rises due to solar radiation during the day and falls due to radiative cooling at night.
-
On Aug. 4, the highest daily temperature was observed to be 36.2℃. The lowest temperature on the 4th was 27.3℃, indicating that the temperature did not drop significantly even at night, suggesting a tropical night phenomenon.
Maximum temperature, Minimum temperature, Average temperature, Daily temperature difference
-
During the entire period, the maximum temperature is maintained in the range of 33-36℃, and the minimum temperature is maintained at 27-29℃.
-
The average temperature overall is high
2. Comparison of 2024 and 2023
Comparison of daily minimum, Average, and Maximum temperature trends
2023/08/01 ~ 2023/08/07
2024/08/01 ~ 2024/08/07
-
Four of the seven days from Aug. 1 were the highest, with a maximum temperature of 36.2°C and a minimum temperature of 27.3°C on August 4th. This is 5.1°C higher than the 31.1°C maximum temperature on the same day of the previous year.
-
Overall, the lowest, average, and highest temperatures in 2024 were all higher than in 2023.
