It's so cold this year that temperatures all over the country have hit new lows. Has the problem of warm winter been solved?
First of all, I personally think that warm winter is not a problem. 77-99 is the warm phase in la madre, which means it should be warm. However, the climate data of China, including foreign countries, are counted from the cold period, and up to now, there is an illusion that it has been warming. In fact, in 2000, the earth entered the la madre Cold Period, and in 2005, 84 years later, China ushered in a normal winter (non-warm winter), while in 2008, the temperature was relatively high, and freezing disasters occurred in the south. At the same time, the unusually cold this winter is obvious to all. In other words, the appearance of warm winter is staged, and in the next 30 years or so, it will be colder than warm winter!
Details are as follows:
From June 5438 to October 2009 10, some scholars in China published articles predicting that the winter in 2009 might be cold for the following four reasons.
Sunspot theory
The low sunspot value in 2009 led to the "cold winter"
165438+20091October 20th Guangzhou Daily reported that recently, parts of southern China suffered from rare low-temperature ice and snow weather. Experts from the Guangdong Astronomical Society believe that this may be caused by the scarcity of sunspots, and the sunspots continue to be depressed, and Guangdong may usher in a "cold winter."
Sunspots are dark spots on the photosphere of the sun, which are the most obvious signs of solar activity. In the past two years, there have been very few sunspots, and the sunspot cycle has been gradually extended. In August, 2009, Yunnan Observatory of the National Astronomical Observatory of Chinese Academy of Sciences did not observe sunspots for 3 1 day.
Are sunspots related to cold damage? Guangdong Astronomical Society believes that there is a high correlation between them. According to statistics, 1986 is a low year for sunspots. From the end of 1986 to the beginning of 1987, low temperature weather occurred in many provinces and cities in China. 1964 and 1954 are low sunspot years, and there are similar statistical results.
Deep sea earthquake cooling theory
The magnitude 8 earthquake and tsunami in 2009 may lead to a cold winter.
In the early morning of September 30th, 2009, Beijing time, an earthquake of magnitude 8 occurred in Samoa, which triggered a tsunami. According to historical records, as far as the global disaster trend is concerned, the tsunami in the South Pacific triggered by the M8 earthquake in Samoa may lead to a gradual decrease in global temperature, trigger a low-temperature freezing disaster and increase the intensity of influenza outbreaks.
After the earthquake and tsunami in Indonesia on June 26, 2004, the global low-temperature freezing injury and snow disaster occurred frequently.
Guo Zengjian, former deputy director of the Seismological Department of Lanzhou Institute of Geophysics, China Academy of Sciences, put forward the theory of "deep-sea earthquake cooling", which is a reasonable explanation: a huge earthquake in the ocean and its surrounding areas produces a tsunami, which can make deep ocean cold water move to the sea surface, cool the water surface and absorb more carbon dioxide, thus cooling the earth for nearly 20 years.
The temperature rise after the 1980s was related to the increase of carbon dioxide emissions caused by human activities, and there was no huge sea earthquake during this period.
According to Guo Zengjian's theory, in 2005, the global temperature will be reduced due to the earthquake and tsunami in Indonesia. Objective practice has made a fair test.
It is universally acknowledged that 1998 is the hottest year on record, and western scientists also acknowledge this objective fact: in the past two years, the change of natural climate has offset the global warming effect, and will continue to make the temperature in 2008 keep a slow change trend. 2008 is the coldest year in the last decade, and 2005 did not break the high temperature record of 1998.
El Nino said
In the cold period of la madre, El Nino and La Nina years are prone to winter.
Statistics show that severe chilling injury in northern China occurred in El Nino years during the cold period of la madre, such as 1957, 1969, 1972 and 1976.
Severe low temperature freezing injury occurred in low sunspot years and La Nina years (or El Ni? o years) during the cold period of la madre in southern China, such as February 1954 ~ 15 to 10/0 1955 ~ 2 1,1in Hunan.
The law shows that the cold phase period in la madre is the concentrated outbreak period and low temperature period of global strong earthquakes.
The rare snow and ice disaster in southern China from June, 5438 to October, 2008 was caused by La Nina events in 2007-2008 during the cold period of la madre from 2000 to 2030. The El Nino event from 2009 to 20 10 may lead to a cold winter.
The theory that the moon causes trouble
The period from 65438+February 2009 to 2065438+February 2000 is a strong tidal period, which may lead to a cold winter.
Charles Gilling of the Institute of Oceanography at the University of California, San Diego, pointed out in the Proceedings of the National Academy of Sciences in 2000 that the moon raises the temperature of the earth by influencing the tides on the earth.
Ji Lin believes that the change of the relative positions of the earth, the moon and the sun will cause the gradual change of tidal intensity.
The sun, the earth and the moon are in a straight line. When the distance between them is the smallest, the tidal forces of the sun and the moon strengthen each other and become the largest, and the ocean tides are the largest. More cold water from the depths of the ocean is brought to the sea surface to cool the air on the ocean.
According to the calculation, the period from February 65438+ in 2009 to February 2000 is a strong tide period, which may lead to the occurrence of cold winter.
