Drought and flood, early flood, many typhoons, rapid cold waves, and early ...... in winterIn the past 2023, the overall weather in Panyu District will be changeable, the temperature will be polarized, and a number of data will reach the "highest" in the same period in history. So, what will the weather be like in 2024? Let's take a look at the weather and climate characteristics of Panyu District in 2023 and the climate trend in 2024** released by the Panyu District Meteorological Department.
Weather and climate characteristics in 2023
The temperature is on the high side. The average temperature in 2023 is 240, 0 higher than the last ten years4, the third highest in history; The highest temperature of the year is 389, the third highest in history. Among them, the average temperature in July is 306, a record high for the same period in history; The highest temperature in May is 389, the highest in the same period in history; The highest temperature in December is 304, tied for the highest in the same period in history.
More precipitation. The precipitation in 2023 is 20056 mm, 7% more than the past decade, and the precipitation before and after is more, and the extremity is strong. Among them, during the "Dragon Boat Water" period (May 21 to June 25), the precipitation was 4327 mm, 17% more than the same period in the past decade; The cumulative precipitation in September was 7236 mm, which is 44 times, the second most for the same period in history (the highest in the same period in history was 1965, 724.).1 mm).
Drought and flood turned sharply. From February 15th to March 23rd, the Panyu National Basic Meteorological Station had 37 consecutive days without precipitation, and the lack of rain, high temperature and strong evaporation led to the development of meteorological drought, which reached the extreme drought level on March 18.
There are many typhoons affected, and there is the most rainy process in history. In 2023, four typhoons will affect Panyu, including "Taili", "Sula", "Haikui" and "Little Dog", of which "Haikui" is particularly severe. On September 7 and 8, under the influence of the remnant circulation of "sea anemone" and the monsoon, Panyu experienced heavy rain to extremely heavy rain, which was the most rainy process since meteorological records (1959), and the average surface rainfall of the whole region was 3437 mm, of which the maximum accumulated rainfall of 6 hours, 12 hours and 24 hours in Nancun Town broke the historical record.
Affected by the cold wave, Panyu experienced the strongest low temperature process of the year on December 16 and 27, with a minimum temperature of 47. The average daily temperature in 48 hours decreased by 170, the largest decline since 1988, ranking second in history; On December 17, Panyu successfully entered winter, which was the "earliest winter" since 1976.
2024 climate**
It is estimated that the average annual temperature in Panyu in 2024 will be 235～24.5, 0 higher than the last ten years1～0.5℃；The annual precipitation is 1650 1850 mm, which is about 1% less than that in the past ten years; The number of typhoons affected is roughly 2 3.
Temperature and precipitation**: Spring (March to May) is on the average 0 percent higher1～0.5, precipitation is more than 1 2 into; In summer (June to August) the average temperature is 05～1.0, precipitation is less than 1 2 percent; In autumn (September and November), the average temperature is normal to slightly high, and the precipitation is normal to more than 1%.
Drought**: At present, there has been a moderate meteorological drought in Panyu, and there is a high possibility of periodic meteorological drought in spring.
Heavy rain**: The number of rainstorm days during the flood season is normal to slightly more, and the precipitation concentration period and typhoons may bring extremely heavy precipitation, resulting in localized floods and geological disasters.
Typhoon**: The number of typhoons affected is normal to slightly less, roughly 2 3.
High temperature**: The high temperature heat damage is a slightly multi-year scenario, and the number of high temperature days is 40 to 50 days.
In view of the current and future meteorological drought phenomenon, Panyu needs to pay attention to strengthening drought monitoring and judgment, strengthening reservoir water storage and water transfer, and doing a good job in emergency guarantee of water supply. In addition, the intensity of heavy rainfall in Panyu has increased in the past decade, and it is expected that the precipitation concentration period and typhoons in 2024 may bring extremely heavy precipitation, so it is necessary to pay attention to preventing flood disasters and geological disasters that may be caused by heavy precipitation.
