Affected by global warming, the Central Meteorological Administration pointed out that the average winter temperature in Taiwan this year is still normal and warm, and the rainfall is normal. There may be strong cold air moving south in early December, and it will be warm in mid-to-late December. It will be warm and good weather with the opportunity to be warm at the end of the year. In addition, in recent years, Taiwan, China has grown longer and shorter in summer. The 16-degree low temperature in Taipei is getting late and late, and the chances of extreme climates have also increased.
Meteorological experts said that the sea temperature near Taiwan, China is relatively warm, and the holy infant phenomenon is not obvious this year. Therefore, the overall temperature in Taiwan this year should be normal and warm, while the rainfall is normal. There may be strong cold air moving south in early December, while it will be warmer in mid-to-late December, and the coldest time will be between January and February. It is still impossible to accurately grasp the weather conditions of New Year's Day and Spring Festival next year. However, in terms of general trends, the end of the year's New Year's Eve is expected to be warmer, while the Spring Festival is the time when the temperature may be the lowest, but the detailed weather conditions still need to be approaching before accurate predictions can be made.
Meteorological experts pointed out that due to the impact of global warming, Taiwan, China gradually grows longer and winters shorter, but this does not mean that there will be no strong cold air masses or cold currents. Taking 2016 as an example, it was a warm winter that year, and there were also overlord-level cold currents. It can be seen that even in a warm environment, there may still be a high-intensity cold current. Pay attention to the frequent alternation of high temperatures. The cold air from the north moved south to affect Taiwan, China. In the past, the time when Taipei City dropped to a low temperature of 16 degrees fell by about mid-to-late November, and this year it only occurred on yesterday and December 2.
The Meteorological Bureau updated the special report on low temperature warning this year. In the past, the temperature below 10 degrees will be released. However, sometimes it is cold in the morning and warm during the day. For the clear distinction, the special report on low temperatures from November 10 this year is divided into three levels, and the temperature below 10 degrees is yellow light; the temperature below 6 degrees or below 10 degrees and the temperature below 12 degrees is an orange light; the temperature below 10 degrees and the temperature below 12 degrees is an orange light; the temperature below 10 degrees and the temperature below 12 degrees is an orange light; the temperature below 10 degrees and the temperature below 12 degrees is a red light; the temperature below 10 degrees and the temperature below 12 degrees is a continuous 24 hours is an orange light; the temperature below 6 degrees is a red light.
Meteorological Bureau data also showed that in the autumn (September to November), there were 16 typhoons in the northwest Pacific this year, which was significantly more than the average climate of 11; among which typhoons invaded Taiwan, and the number of typhoons invaded Taiwan was close to the average climate of 1.2. The Meteorological Bureau further pointed out that the average temperature in Taiwan is warmer this fall. In terms of rainfall, except for the normal coastal areas in the north and southern regions, the rest are significantly less. Alishan , Yushan and Penghu set a record of the lowest rainfall in autumn since the stations were set up.
The first wave of mainland cold air masses in winter has shown signs of power. This morning, the whole of Taiwan was frozen rapidly, but there was a cold air relay afterwards. Meteorological experts said that another wave of strong cold air flowed south on Friday, and the temperature dropped again. The temperature dropped to the lowest on Saturday night and Sunday morning, and the open and flat ground will still drop very low due to radiation cooling. The weather risk company reminded that the forecast rainfall in northern and Yilan on Thursday is quite heavy, which is an unusual rain signal in winter, so you should pay attention to the occurrence of related disasters. The latest European Medium-term Forecast Center (ECMWF) mode simulation shows that the influence of dry cold air today, the water vapor gradually decreases, and the northern Taiwan turns cloudy, the temperature is still low, and the central and southern parts are clear and stable, comfortable and cool during the day, and cold in the morning and evening, so you should pay attention to keeping warm.
Meteorological experts said that the Meteorological Bureau’s path potential forecast map shows that the central Taipei corona travels westward through the central part of Philippines today, and then enters the South China Sea due to the damage of the terrain; on Wednesday, there was another strong vertical wind cut, and the intensity continued to weaken, and the water vapor was transported to Taiwan. The cloud volume in various places gradually increased, and the rainfall became more and more obvious. On Thursday and Friday, the water vapor of the North Corona enveloped Taiwan. In addition to the windward and mountainous areas, there was also significant rainfall in the central and southern regions, which rarely rained in winter. Although the cold air has weakened slightly on Wednesday and Thursday, due to the heavy clouds and the temperature difference between day and night, the central and southern regions also feel wet, cool and slightly cold all day, so you should pay attention to keeping warm and rainproof.
Meteorological experts remind that the air conditioner weakens slightly on Wednesday, and the low temperatures in various places will rise by 2 or 3 degrees. However, the water and gas relay brought by the northern crown typhoon in the south will turn north, and the feeling of wet and cold may be even more annoying. Especially on Thursday, the rain forecast in the northern and Yilan is quite heavy. In addition to the water and gas brought by the typhoon, there is also an unstable system in the middle of the atmosphere to cooperate, which is an unusual rain signal in winter. Pay attention to the occurrence of related disasters.
