La Nina is back. It's very cold in winter. What's the impact on us? La Nina phenomenon is the opposite of Urbana phenomenon. The annual seawater temperature in La Nina is 0.5 or lower than that in normal years. La Nina, the trade winds in East Asia are strengthened, and the main monsoon rain belt in China is northward in summer. It is more likely that there will be drought and little rain in the Jianghuai basin, while it will be rainy in the north, especially in the North China-Hetao area. In autumn and winter in La Nina, there is more precipitation in most parts of the north, less precipitation in most parts of the south and less snowfall in the Qinghai-Tibet Plateau in winter. La Nina years, China is often hot in winter in Leng Xia. There are more typhoons landing in China in the northwest Pacific and South China Sea than normal, but the intensity is weak.

So, what is La Nina? The National Oceanic and Atmospheric Administration (NOAA) of the United States defines El Ni? o and La Ni? a as two opposite stages of the tropical Pacific natural climate model, which fluctuate back and forth every 3-7 years. Together, they are called ENSO, which is the abbreviation of El Nino-Southern Oscillation. The ENSO model in tropical Pacific may be in one of three states: El Nino, neutral or La Nina. La Nina phenomenon: the sea surface in the central and eastern tropical Pacific becomes colder or lower than the average sea surface temperature (SST). In Indonesia, rainfall tends to increase, while rainfall in the central tropical Pacific decreases. The normal easterly winds along the equator become stronger.

Although La Nina phenomenon is not equal to 1, 000% is equal to the cold winter, from the experience in the past five years, when La Nina phenomenon occurs in China, the temperature in most parts of the country will be low. For example, during the Spring Festival in 2008, a large area of southern China suffered from the once-in-50-year low-temperature rain, snow and freezing weather. If there is a strong La Nina phenomenon this winter and next spring, the global demand for coal, natural gas, oil and other energy sources will increase substantially, and the power gap caused by the superposition of double carbon will push up the prices of related varieties. The corresponding stock needs to consider the multiple effects of limited production, rising costs and rising product prices to judge whether the whole stock is beneficial or damaged, which will also determine the trend of the stock price.
