In February 2024, a
high-pressure area from China extended its influence over upper Thailand for
the entire month. Its effects begin particularly pronounced in the middle of
the month, when a moderate to active high-pressure area covered the mentioned
regions. Additionally, the westerly winds at upper levels shifted to cover the
northern and northeastern parts at the beginning of the month. This led to
cooler weather in various parts of Thailand, especially in the northern and
northeastern regions, where most areas experienced cool conditions and several
areas encountered cold weather. Towards the end of the month, a heat-induced
low-pressure cell enveloped upper Thailand, resulting in a relative increase in
temperatures and widespread hot conditions across most areas of the country.
The monthly mean temperature in Thailand was 1.6°C above the norm, with some
stations recording new highest maximum temperatures (see Table 1). In terms of
precipitation, upper Thailand experienced intermittent rain, while the southern
region received rainfall mainly along the east coast, particularly in the
middle of the month. This was influenced by an active northeast monsoon that
prevailed over the Gulf of Thailand and the southern part, coupled with
southerly winds prevailing throughout the month. The average total rainfall in
Thailand for this month was approximately 63% below the norm, with all regions
reporting below-normal monthly rainfall: the northern region received 8.8 mm
(90% of the norm), the northeastern region 13.7 mm (88%), the central region
8.7 mm (71%), the eastern region 4.5 mm (16%), the southern region (east coast)
23.6 mm (59%), and the southern region (west coast) 23.9 mm (79%). More details were as follow.
