Which areas in Germany have temperatures similar to those in China?

Germany mostly has a temperate maritime climate. According to latitude and longitude, Germany is at almost the same latitude as Heilongjiang in China and even reaches Russia, but their climates are very different. China's coastal cities such as Tianjin, Qingdao, and Shanghai have a temperate monsoon climate, which is very different from the temperate maritime climate. So not only does China not have cities with a temperate maritime climate, but neither does the whole of Asia.

Germany is located in the warm and humid westerly belt and has a transitional climate between the maritime climate of Western Europe and the continental climate of Eastern Europe. The northwest mainly has a maritime climate, which is not hot in summer and not cold in winter, making it relatively comfortable. The continental climate in the east and southeast has significant characteristics, with cold winters and hot summers. The coldest temperature can reach -10 degrees and the hottest temperature exceeds 30 degrees.

Smooth and mild are the overall characteristics of Germany's climate, with relatively stable temperatures. The average winter temperature is between 1.5 degrees (lowlands) and -6 degrees (mountainous areas), and the average summer temperature is around 18 degrees (plains) to 20 degrees (southern valleys). Usually April is the month with the most unpredictable climate changes in Germany, with heavy rains, hurricanes, snow and hail coming alternately, so it is best to bring rain gear when going out during this time; May, June, September, October, and November are the most popular months for Germans It is a good time to engage in various exchange activities, and various activities are generally arranged within these five months; July and August are the vacation seasons for Germans, and they are also the peak tourism periods in Germany; the sunset in Germany is earlier in winter , rainy and snowy.

China is located in the southeast of Eurasia, the largest continent on earth. Due to the different physical properties of sea and land, especially the differences in thermal effects, the Asian continent is the source of cold air in winter, forming cold high pressure, and the cold air radiates from the continent to all directions; in summer, the land heats rapidly, forming thermal low pressure, and warm and humid air flows from The surrounding ocean blows toward the low pressure center. This change in the prevailing wind direction in winter and summer brings obvious seasonal changes in climate, which forms China's monsoon climate.

The cold high pressure on the winter monsoon continent formed in September, with its center located in Mongolia. The cold and dry northwest or northeast monsoon blows out, first reaches northern China, and soon advances southward to the Yangtze-Huaihe River Basin and the areas south of it. The winter monsoon strengthens month by month with seasonal changes, and is strongest in January. Cold air breaks out southward every 7 to 10 days, and can drop by 12 to 16°C in 24 hours in southern China, sometimes accompanied by moderate to heavy rain. Hainan Island can also cool down by more than 8℃. When cold air reaches the southern coast, low clouds often form, accompanied by drizzle. When the winter monsoon is strong, it can blow as far as northern Australia, which is the southernmost limit of the winter monsoon. Cold and warm air from the northern and southern hemispheres often mix in this convergence zone or the intertropical convergence zone. At this time, the winter monsoon blowing from the Asian continent forms a north-south direction after meeting the cool and moist airflow blown by the subtropical high in the North Pacific over the western Pacific. Convergence lines, where precipitation is relatively abundant. The winter monsoon only prevails at low altitudes (below 3,000 meters). The average altitude of the Tibetan Plateau in southwest China is above 4,000 meters, so it is difficult for cold air to cross the Tibetan Plateau. The winter monsoon flows along the east side of the plateau and to the east of China towards eastern China. Cold air often moves south along with the cold front. It is windy and sunny in the north, but moves slowly to the Jianghuai and south areas. In the Yunnan-Guizhou Plateau, a stationary front often forms, manifesting as a wide range of cloudy and rainy weather.

The Asian continent heats up rapidly in April and May during the summer monsoon, forming a thermal low pressure, with its center located to the west of the Tibetan Plateau. The warm and humid air diverged from the Pacific subtropical high reaches deep into the north and the Hetao area from the southeastern coastal areas in the form of southeastern or southern monsoons. Its climate characteristics are hot and humid with frequent thundershowers.

The summer monsoon that affects China comes from three sources: the first is the southwest monsoon originating from the southern Indian Ocean, forming a low-altitude jet stream in the Arabian Sea, passing through the Indian Peninsula and affecting southwest and southern China; the second is The southeast trade wind originating from northern Australia crosses the equator through Indonesia or the Malay Peninsula and merges with the first airflow and the northeastern trade winds in the northern hemisphere to form the equatorial convergence zone; the third airflow originates from the North Pacific subtropical high, which is the main influence Southeast monsoon and south monsoon in eastern China. They penetrate deep into the northwest of Northeast China and the northern part of Inner Mongolia, which is the northern limit of China's summer monsoon. When it meets the cold air from the northwest, it forms a heavy rain belt, bringing abundant precipitation. This heavy rain band usually represents the activity of the summer monsoon. There are two rapid advances and one rapid retreat in the East Asian summer monsoon. Generally, the summer monsoon prevails in South China in early May, which is the beginning of the monsoon rain in South China; it prevails in the southwest region in late May or early June; and it suddenly prevails in the Jianghuai River Basin in mid-June, which is the beginning of the plum rain season in the Jianghuai River Basin. In mid-July, the summer monsoon once again jumps northward to North China and Northeast China, which is the beginning of the rainy season in the north. It is also the end of the rainy season in central China and the onset of drought. By mid-to-late August, it is the peak period of the summer monsoon, and at this time it advances to the highest point in China. Northern and westernmost limits. Therefore, it takes about 4 months for summer monsoon activity to travel from South China to the northern areas of North China. And its retreat is another sudden change. Generally, the cold air in the north begins to strengthen in early September, that is, the winter monsoon begins to establish. The arrival of winter monsoon only takes one month, and it will soon reach South China or coastal areas from north to south. The advance and retreat speed of the Chinese summer monsoon is exactly opposite to that of the Indian monsoon in another famous monsoon area. The Indian summer monsoon comes in an explosive manner, taking only 1 month from south to north, while its retreat takes 4 to 5 months. .
