According to monitoring data from the National Climate Center, a moderately strong El Niño event has formed and will continue until the spring of 2024. In the context of global warming, from this winter to next spring, the temperature in most parts of China is expected to be close to the same period of the year or high, that is, this year is likely to be a "warm winter".
El Niño is a climate phenomenon in which the sea surface temperature in the eastern equatorial Pacific Ocean continues to be high and causes anomalies in atmospheric circulation. It raises the temperature, while La Niña, on the contrary, lowers the temperature. Therefore, El Niño does not mean that winters will not be cold. In addition, despite the El Niño, periods of cold air remain active, which can lead to sudden large cold spells that bring extreme weather events such as cooling, snowfall, and freezing.
The El Niño phenomenon has had a non-negligible impact on global agriculture. For example, Chile's early-maturing cherry crop was halved by the El Niño phenomenon that triggered massive heavy rainfall, just as the early-maturing cherries were about to ripen and go on the market. El Niño can also lead to problems such as abnormal crop growth and development, pest and disease outbreaks. Therefore, farmers need to pay close attention to the weather forecast and take timely measures to protect their crops.
1.Frost Preparedness: The probability of a cold spring has increased this year, especially in warmer years in the early part of winter. The inverted spring cold refers to the unusually low temperature weather that occurs after the temperature rises in spring, which can cause serious damage to crops that are just beginning to grow and flower. Farmers should choose cold-tolerant crop varieties in advance, carry out field management in a timely manner, and take cold protection measures.
2.Rain, snow and ice: Periodic low temperature rain, snow and freezing weather may occur in the southern region, which will adversely affect agriculture. Farmers should pay close attention to weather changes and take timely drainage and anti-freezing measures to reduce frost damage to crops.
3.Extreme weather prevention: Due to the El Niño phenomenon and periods of cold air activity, extreme weather events may increase, such as major cold waves, major cooling, snowfall and freezing. These weather events not only affect daily life, but also adversely affect crops. Farmers should pay attention to the weather forecast and take timely measures to protect their crops.
For farmers, prevention and preparedness are key to dealing with the effects of El Niño. On the one hand, they should keep abreast of weather changes and take effective countermeasures before extreme weather occurs by paying attention to weather forecasts and meteorological warning information. On the other hand, farmers should also strengthen the cultivation and management of crops, such as selecting crop varieties adapted to the local climate, strengthening field management measures, and establishing a sound disaster prevention and control system. In addition, they should strengthen the construction and maintenance of agricultural infrastructure and improve the resilience of farmland.
The efforts and preparedness of farmers are key to ensuring the stability of agricultural production. Only by fully understanding and responding to uncertain weather conditions can they take appropriate measures to protect crops and reduce losses. At the same time, ** and relevant departments should also provide scientific meteorological forecasting services, increase policy support and technical guidance for farmers, and jointly respond to the challenges brought about by the El Niño phenomenon.
The formation of the El Niño phenomenon and its impact on agriculture require our great attention. As an important player in agricultural production, farmers need to remain vigilant in the face of El Niño and take appropriate measures to deal with it. Adverse impacts on agriculture can only be minimized by paying close attention to meteorological changes, strengthening crop management, and establishing a sound disaster prevention and mitigation system. At the same time, ** and relevant departments should also increase support for farmers and provide necessary policy and technical guidance to jointly address the challenges posed by the El Niño phenomenon.
In short, farmers should be prepared for El Niño. At the same time, we should also be aware of the reality of global warming and increase efforts to protect the environment and combat climate change. It is only through joint efforts that we can protect our agricultural production, ensure food security and the interests of farmers, and achieve the goal of sustainable development.
