Temperature in Dalian in 2024 Super El Nino Year

Temperature in Dalian in Super El Nino Year 2024: This winter (65438+February 2023-February 2024), the average temperature in the whole province is -7.0℃~-6. 1℃, which is 0. 1℃ higher than normal. In June 2024, there was frequent cold air activity in 5438+ 10, and there may be staged low temperature weather.

In the winter of 2023-2024, the El Ni? o event will continue to stimulate the anticyclone in the northwest Pacific Ocean, and the southerly wind in the northwest will be transported to Liaoning Province, with relatively good water vapor conditions, so there may be a heavy snowfall this winter. Affected by it, abnormal anticyclone circulation prevails in the lower troposphere over the northwest Pacific and the South China Sea in winter, the East Asian trough is weak, the winter monsoon in East Asia is weak, and the temperature in most parts of central and eastern China is higher than normal.

On the other hand, the abnormal anticyclone circulation is beneficial to the transport of warm and humid water vapor from the tropics to the south of China, and it is easy to cause more precipitation in the south with the cooperation of cold air activities. Statistics show that under the background of El Ni? o event, the temperature fluctuates greatly in winter, and the amount of cold air affecting China is often too large. Meteorologists reminded that we should pay close attention to the possible adverse effects of the staged low-temperature rain and snow weather process.

The weather phenomenon of El Nino warm current;

The word El Nino comes from Spanish El Nino? O, which originally means "little boy", also refers to the baby, that is, Jesus. It is used to indicate that the sea surface temperature on the west coast of South America (near Peru and Ecuador) extends westward and reaches the international international date line through the equatorial Pacific Ocean.

In normal years, trade winds prevail in the southeast of this area. The easterly stress on the equatorial surface transports surface warm water to the western Pacific Ocean and accumulates there, which leads to the rise of sea level and seawater temperature there. In the East Pacific Ocean, under the action of the near sea breeze, the surface seawater drifts offshore, which leads to the continuous divergence of seawater quality, the decline of sea level and the upwelling of cold water in the lower layer, which leads to the decrease of sea surface temperature here.
