The North will welcome the first cold air wave on September 21-22. From September to October, cold air operates with a low frequency and weak intensity, the weather has not had a clear change. The time when cold air increases in both intensity and frequency is information that people are interested in.
Lao Dong Newspaper reporter discussed with Mr. Nguyen Duc Hoa - Deputy Head of Climate Forecast Division, National Hydrometeorological Forecasting Center about this issue.
Sir, when is the forecast for cold air to be most active this year and will there be more or less severe cold?
- Cold air is likely to be active from November to December 2024. By January to February 2025, cold air will continue to increase in intensity and frequency and is likely to continue to cause widespread cold spells in the northern provinces. January and February are also the coldest months of the year.
It is predicted that this year's winter temperature will be 0.5 degrees Celsius lower or approximately the average of many years. The number of days with severe cold will likely appear more than in the winter of 2023 - 2024.
What is the forecast for the lowest temperature that can be recorded this winter, sir?
- Last winter, the temperature in the North was 1 - 1.5 degrees Celsius higher in all months, and 2 degrees higher in some places. In November - December this year, the temperature may be 0.5 degrees Celsius lower. In January - February 2025, the temperature is forecast to be approximately the average of many years.
In January, the Northern Delta usually has an average temperature of about 16.5 - 17 degrees Celsius. With such a low average temperature, when strong cold air arrives, it can cause a sharp drop in temperature, causing severe cold. Below 15 degrees Celsius, severe cold will occur, below 13 degrees Celsius, severe cold will occur.
The lowest temperature in the plains can drop to 7 - 10 degrees Celsius, in mountainous areas 0 - 4 degrees Celsius, and in high mountainous areas it can be below 0 degrees Celsius.
It is necessary to guard against the possibility of dangerous weather phenomena such as frost, ice, and snow in the mountainous provinces of the Northern region during the winter months.
Sir, besides cold air, what other notable weather phenomena should we pay attention to at the end of the year?
- We have continuously warned of the phenomenon of storms and floods in the Central region, especially in October, November and even December. Storms and floods are forecasted to be more frequent than the average of many years.
Thank you very much!
