Why was there a weather anomaly in the summer of 2022?

In the summer of 2022, there was an anomaly, all because of the relatively large impact of the environment, this summer was relatively hot, and the north continued to have high temperatures.

This year's environment is more abnormal, and human activities are more frequent, so the climate is more abnormal.

This is due to the influence of La Niña events and the abnormal temperature of the sea in the tropics.

La Niña (Spanish: la ni a).

In contrast to the warming of the east-central Pacific Ocean during El Niño, La Niña is an abnormally cold condition in the east-central Pacific Ocean. The southeast trade winds blow the sun-scorched sea water from the surface to the western Pacific Ocean, increasing the sea level in the western part by nearly 60 cm compared with the eastern part of the Pacific Ocean.

The atmospheric circulation over the Pacific Ocean is called the Walker circulation, when the Walker circulation becomes weaker, the sea water cannot blow to the west, and the sea water in the eastern Pacific Ocean warms, which is the El Niño phenomenon; But when the Walker circulation becomes unusually strong, La Niña occurs. Generally, La Niña occurs with El Niño, and the second year of El Niño occurs, La Niña occurs, and sometimes La Niña lasts for two or three years.

In recent years (2009-2011), winter snowstorms have been frequent, resulting in frequent winter snowstorms due to the melting of Arctic glaciers and the flow of cold fresh water near the sea, resulting in the La Niña phenomenon.

Effect. La Niña causes anomalies in the global climate. Impacts include:

It has made the southwestern United States and the west coast of South America unusually dry, and has caused unusually high rainfall in Southeast Asia such as Australia, Indonesia, Malaysia and the Philippines, as well as unusually cold on the west and southeast coasts of Africa, Taiwan, Japan and the Korean Peninsula. In the Northwest Pacific region, tropical cyclones will affect areas that are more southerly and westerly than normal.

In addition, the subtropical high will be stronger than normal, causing the tropical cyclone to move west-northwestwards and more tropical cyclones in the Philippines and the South China Sea.

Interestingly, once La Niña occurs, hurricanes in the North Atlantic can also be unusually active. For example, the 2005 Atlantic hurricane season saw four rare Category 5 hurricanes with the highest intensity, in that order:

Hurricanes Emily, Hurricane Katrina, Hurricane Rita, Hurricane Verma, and earlier in the 1998 Atlantic hurricane season, Hurricane Mitch, caused heavy human life** and home damage in North and Central America.

In the summer of 2022, there will be continuous rainfall and snowfall in some parts of our country, which is extremely abnormal, and the reason is caused by the La Niña phenomenon and the abnormal tropical sea temperature, which will slowly recover in the future!

There are a lot of anomalies, so it's caused by the polluted environment, and this is terrible.

Be. It is mainly caused by La Niña events and tropical SST anomalies. Because according to the ** situation of the climate center of our country.

As a result, the summer of 2022 is likely to experience La Niña. It is expected that China's climatic conditions will deviate in the later period, and there will be both drought and flood, and regional.

There are two reasons for the abnormal weather in 2021:

1. There are more extreme weather events.

2. Meteorological annual deviation and extreme weather are frequent.

In 2021, in addition to the strongest sandstorms in most parts of China, typhoons in southern Jiangsu caused more than a dozen deaths and snowfall in many places.

Internationally, Houston, Texas was hit by a snowstorm, millions of customers suffered power outages, locust plagues in Kenya in Africa, and volcanoes in Europe that lasted for months, among others. The global climate seems to be abnormal, in the final analysis, it is caused by the rise in global temperature, sea level, global warming, the obvious "greenhouse effect", and abnormal climate.

Main technical measures for agricultural disaster prevention and mitigation:

1. Prevent low-temperature freezing damage in the northern winter wheat area, strengthen field management and promote strong seedlings.

Wangchang wheat fields should be carried out in early spring to suppress squatting seedlings in a timely manner to achieve the control of prosperity and turn strong. Timely topdressing of weak seedlings, reasonable regulation of fertilizer and water, promotion of seedling transformation and upgrading, and improvement of cold and frost resistance. Comprehensive measures to prevent frost damage.

In wheat fields that have suffered from frost damage, appropriate nitrogen fertilizer should be applied in time and watered in time to promote the recovery of the growth of frozen wheat.

2. Prevent summer floods in the Huang-Huai-Hai area and do a good job of defense in advance.

Strengthen the monitoring of rain, water, moisture and seedlings, release early warning information in a timely manner, clear ditches and manage moisture in advance, prevent waterlogging and reduce stains, and prevent large-scale waterlogging. Stock up on supplies in advance. Do a good job in the maintenance of flood drainage equipment, timely transfer and transportation of diesel, water pumps, seeds, fertilizers and other materials to ensure the needs of flood control and drainage.

The weather is so abnormal, indicating that the environment is seriously pollutedExtreme weather is very much, and it is really important to protect the environmentOnly by controlling carbon emissions can society developNow the weather is extremely abnormal, whether it is the interaction of hot and cold weather or other aspects, it is a very abnormal state. There is nothing wrong with protecting human beings and protecting human beings, because only by controlling carbon emissions can society develop sustainably. Now everyone is not aware of the harsh environment, and one day there will be a price.

Because everyone's life is under too much pressure, what we need more than high temperature is to make money to live, as long as we make money and work to live, we have no time to care about abnormal weather.

I think everyone has realized that the weather this year is indeed very abnormal, especially in the summer, the weather will be very hot, and after entering the autumn, many areas have begun to cool down rapidly, some places have a lot of precipitation, but some places are particularly dry.

These symptoms belong to a rare sleep disease: narcolepsy, the incidence of which is in nearly 700,000 people across the country, but less than 5,000 people are diagnosed. The gap in the middle is that the vast majority of us are misdiagnosed.
