In the history of Hainan, there have been many extreme weather records such as snowfall, hail, hurricane, rainstorm and drought, which have greatly affected local production and life.

It also hails 20 1 1 in Danzhou.

Hail in Hainan mainly occurs in March-May, of which March accounts for 48% of the records, April accounts for 29%, and there is basically no hail in the rest months. The hail area is mainly in the inland area of the northern half of Hainan.

Wu Hui, a meteorologist at Hainan Climate Center, said that hail was rarely observed in Hainan in recent decades. The last hail with meteorological observation records in Hainan occurred in Danzhou on May 20 1 1 year.

Although hail is rare, it will destroy crops and houses and hurt people and animals. Historically, hail has also brought natural disasters to Hainan many times. According to early historical records, in February of the fifth year of Tianshun in Ming Dynasty (146 1), hail fell from the sky in Qiongshan area, "as big as a bucket and as small as a goose egg". Since the Republic of China, the historical records of hail disasters have been gradually detailed. In the 9th year of the Republic of China (1920), on the night of February 18th, there was a sudden hailstorm in Wenchang. "The smallest room is only two or three square inches, and the largest room is square feet." Most houses in the northern area were damaged and the rafters were exposed. The yard was full of hail, which blocked the ditch and knocked out the walls. All kinds of vegetation and plants have "almost no leaves", and many animals such as birds and snakes have also been killed.

It snowed in Wanning in Ming Dynasty.

In the year of Zheng Deyuan (1506), there was a cold wave in the south of China, and even snowfall occurred in Wanning.

Zheng De's Records of Qiongtai contains: Ice Cave, Rain and Snow in Wanzhou, which was written by Wang, a native of Wanzhou (now Wanning) in Ming Dynasty, as Long song. Wang was a juren in the fifth year of Hongzhi, and was once the magistrate of Xuanhua (now Yongning County, Guangxi).

This poem truly describes the scene of snow at that time, leaving precious information for history. "Sprinkle salt and fly with the wind, and you should pick up countless trees. Wei Yanhan penetrated the marten and fur, and suddenly went all over Dongshan Road. " The beginning of the poem is the snow scene in the northern winter, but this is actually a real scene on the land of Qiongzhou.

The strange snow surprised the local people. "The old man never tires of listening all day and does everything he can. The world suddenly regards it as auspicious, and it is not bad to say that it is not a birthday. "

Because of the sudden snow, betel nut fell from the tree. How can a man deserve such a tree? I saw that when it snowed that night, every household was rummaging through the closet to find thick clothes to keep out the cold, and the children were still warming themselves around the stove. Wang couldn't help sighing: "It's a strange thing once in a hundred years."

"Have you ever heard of the classics of war? When locusts enter the ground, wheat seedlings grow. If you don't fall hard, you can get spring ice when you come to Korea. Since ancient times, there has been a saying in China that "Wanzhou snow is a good omen for a bumper harvest in the coming year".

Not only has it snowed in Wanning, but it has also rained and snowed in Lingao, Qiongshan and Chengmai. In the ninth year of Chongzhen in the Ming Dynasty (1637), on December 15, Lingao County "rained and snowed for three nights, and the trees withered" (Guangxu Lingao County Records); In November of the 23rd year of Emperor Kangxi of Qing Dynasty (1684), Qiongshan was "rainy and snowy, flowers and trees fell, and most of the coconuts and hawthorn died" ("Xuan Tong County Records of Qiongshan"); In the 20th year of Jiaqing (18 15), in November, Chengmai County was hit by "heavy snow and trees were injured by rain" (Guangxu Chengmai County Records).

East Lingao once had "rain and blood"

Looking through the historical materials of local county annals, the reporter found that the most recorded abnormal phenomenon was the appearance of comets. During the Ming and Qing Dynasties and the Republic of China, comets were recorded all over Hainan.

The level of ancient science and technology was not high, and people lacked understanding of various natural phenomena. The appearance of comets is often regarded as an ominous omen of war, casualties and so on. Therefore, in the local county annals, whenever there is a comet record, it is often accompanied by disaster. For example, Guangxu's Asia Chronicle records that in the thirty-ninth year of Wanli (16 1 1), the comet saw the south. The following year, Rojo and others rebelled in Lee. Soldier collection. " "In the forty-first year of Kangxi (1702), I saw a comet again. In March, Dongmen Street was burned and four people were injured. " According to the Records of Danxian County in the Republic of China, a comet appeared on the evening of August 2nd in the second year of the Republic of China (19 13). On the 26th, there was an earthquake. "

A rare natural phenomenon of "rain and blood" appeared in Lingao and Thanksgiving (now Oriental City) in Qing Dynasty. "In the fourth year of Shunzhi (1647), it rained on May 22nd in summer, and all the natives were naked" (Guangxu Lingao County Records);

"(Guangxu) leap twenty-nine years in May, Bao Shang village saw fire as big as a bucket, and the color was blue and turbid. From the ridge, volley shot, shot to the west of the village. When I went to visit the next morning, I saw that the water in a pond became turbid, and all the fish and shrimp died, floating on the water and stinking. Some people suspect that the fire they saw at night fell here. Rotation, blood rain. " (Thanksgiving County Records of the Republic of China)

The reporter checked the information and found that the phenomenon of "rain and blood" also occurred abroad. On July 25th, 20001year, it suddenly rained "red rain" in Kerala, western India, and blood-red liquid rained intermittently for two months. In some areas, there is heavy red rain, and the coast and rivers are dyed bright red. After investigation by scientists, there are two main theories: one is that before the rain, the strong wind brought red soil in the Arab region, and with the rain, the red soil mixed with rain fell, making the rain turn red. But this statement was opposed by many people on the grounds that it rained for too long.

Another view is that after research, red sediments are not dirt or dust at all, but alien bacteria. Some scientists boldly put forward that it is an alien creature from a comet, and the red rain may be "an alien creature that landed on the earth."

Besides comets and rain and blood, the juxtaposition of five-color clouds and two days has also been recorded by historians.

It may snow in Hainan in the future.

Why does it snow in Hainan history? Will this miracle happen again in the future? Wu Hui analyzed this natural phenomenon from a scientific point of view. She introduced that the earth was formed about 4.6 billion years ago, and the climate on the earth experienced long-term drastic changes, with about 6-7 major ice ages. The Great Ice Age can be divided into glacial and interglacial periods, in which the climate was colder and the interglacial period was warmer.

Wu Hui said that the Holocene Great Warm Period (the warmest stage of the interglacial period) in Hainan Island began about 7,400 years ago and ended 2,700 years ago, after which the temperature began to drop. The Ming dynasty is in this cold cycle, so it is not surprising that there is snowfall.

The climate of Hainan Island is characterized by obvious alternation of cold and warm, with both periodic evolution and instability. If we don't consider the influence of human activities, only from the perspective of natural climate fluctuation, there may still be snowfall in Hainan Island in the future, but the specific time is difficult to predict.
