Taiwan’s Central Weather Bureau Director Zheng Mingdian shared satellite water vapor channel images on April 2, explaining that the map clearly shows that the sky over Taiwan is particularly dry, so today and tomorrow will be very “baked” (taken from Zheng Mingdian Facebook)
Since the typhoon season in 2020, Taiwan’s rainfall has been low, and so far it has not been able to wait for large-scale rainfall, resulting in severe water conditions everywhere. Taiwan’s Central Weather Bureau chief Zheng Mingdian recently posted the rainfall distance level map for the last three months on Facebook, and specifically marked Taiwan’s location, saying straight away that this drought is coming for Taiwan.
Due to the poor rainfall situation for a long time, Taiwan is facing the most severe water situation in 56 years, and the water storage in reservoirs all over the world has seriously decreased. Tainan and Kaohsiung have started to reduce the amount of water supply, Miaoli and Taichung (including North Changhua) area from April 6 will be implemented “for 5 stop 2” zoning water supply.
The drought problem has seriously impacted the people’s livelihood, causing people to be concerned about when the water shortage problem can be alleviated. However, according to the long-term weather outlook of the Central Weather Bureau, the model predicts that the rain situation in April is still not optimistic, and the rainfall in May and June is normal to low; the average temperature of the whole Taiwan in the coming season (April to June) is normal to warm.
Central Weather Bureau Director Cheng Ming-Dian posted the satellite water vapor channel image on Facebook today (April 2), saying that this is the image of middle and upper level water vapor, the sky over Taiwan is very dry, today and tomorrow will be very “baked”, reminding people to pay attention to hydration.
Yesterday (April 1), Cheng Mingdian posted the U.S. Climate Prediction Center’s “rainfall levels over the past three months” map, and deliberately circled Taiwan, exclaiming that “this drought seems to be very targeted, the scope is not large, on Taiwan.
Zheng Mingdian explained that the green part of the map is more rain than the climate average, brown is less rain than the climate average. The largest brown block in the map, and the largest green block immediately adjacent, indicates the tropical convection zone in the South Pacific, known as the South Pacific Convergence Zone, which is significantly weaker and slightly southwest of its location. An east-west green block near the equator in the northern hemisphere indicates a tendency for the intertropical convergence zone in the northern hemisphere to become active earlier.
However, Zheng Mingdian also said that the Indian Ocean summer winds are brewing, will bring summer convective rain for southern China, is expected to bring Taiwan “before the plum rains precipitation”.
