The weather is getting warmer and warmer
According to the statistics from the National Center for Hydro-Meteorological Forecasting, from the beginning of October 2022 until now, although there have been still cold air waves, only one from 18th October to 20th October actually caused cold weather in the North. The lowest temperature is normally between 14-17 degrees Celsius, and getting lower in mountainous areas, in which, the high mountains in many places are below 11 degrees Celsius. Besides, the Gulf of Tonkin area has observed strong northeasterly winds of level 6 and gusts of level 7. In November, the average temperature in the North and the North Central region is 0.5 degrees Celsius higher than the average for many years. Around the middle of the week and the second half of December, the North of our country will receive the first cold and damaging cold wave in the winter of 2022.
The global climate forecast analysis model (GFS) shows that the northern provinces of Vietnam will have an average temperature of 1 - 1.5 degrees Celsius higher than the average in the period 1980-2009, then, the average temperature in the North Central region will be 0.5 - 1 degree Celsius higher than average. The temperature in the southern provinces will remain unchanged compared to every year.
The years 2018, 2019, 2020 are on the list of 5 years with the warmest winter in the period 1986 to 2020. Number of days of extreme cold with average daily temperature below 15 degrees Celsius and number of days of severe cold with average daily temperature below 13 degrees Celsius also decreased significantly.
In Vietnam, according to statistics nearly 60 years ago, the number of cold air waves pouring down from Siberia has decreased sharply. Normally, each year, there are 29-30 cold air waves, but in the past 10 years, it has decreased to 25 times. In particular, from 2019, only 17 cold air waves from Siberia poured into our country.
According to estimates of the United Nations Economic and Social Commission for Asia and the Pacific (ESCAP), there are 48.3 million people in Asia directly affected by natural disasters, especially storms and floods. This resulted in about 4,000 deaths, about 80% of which is due to flooding. Overall, it is estimated that natural disasters resulted in a total economic loss of USD 35.6 billion, higher than the average of the past two decades, especially damage from droughts, floods and landslides.
