Who can tell me the weather characteristics of Japan, America and France in four seasons?

Japan is an island country in the North Pacific Ocean in the east of the Asian continent. It consists of four large islands and more than 3,000 surrounding islands, with a total area of 377,708 square kilometers. Japan is located in the north temperate zone with a mild climate. But the distance from the northern end to the southern end of Japan is over 3000 kilometers (1, 800 miles), so the climate depends on the time and place where you travel.

The climate change in four seasons in Japan is very obvious. As far as Tokyo is concerned, it is about 2-3 degrees Celsius lower than Taipei or Hong Kong in summer and about 10 degrees Celsius lower in winter. Japan is one of the countries with the highest population density in the world, mainly concentrated in the narrow plains along the Pacific coast.

The United States has almost all climate types in the world. There are few serious droughts and floods in major agricultural areas, and the temperature is mild, so enough rainfall can be obtained.

The climate in the United States is mainly influenced by the Arctic airflow, which brings a wide range of low pressure from the Pacific Ocean every year. When these low pressures pass through the Sierra Nevada, Rocky Mountains and Cascade Mountains, they carry a lot of water. When these pressures reach the Central Plains, they can recombine, leading to the meeting of major air masses and severe thunderstorms, especially in spring and summer. Sometimes, these rainstorms may join other low pressure, continue to spread to the east coast and the Atlantic Ocean, and evolve into a more intense northeast storm (Nor'easter), resulting in large-scale heavy snowfall in the northeastern United States and the mid-Atlantic region of New England. The vast grasslands of the Great Plains have also formed many of the most extreme climate change phenomena in the world.

The washbasin area and the principle of Columbia River height are arid areas with little rainfall, and the average rainfall in the driest time is less than 15 inch (38 cm). The southwestern United States is an arid desert. In the hottest weeks of summer, the temperature exceeds 100 degrees Fahrenheit (38 degrees Celsius). The southwest and washbasin areas will also be affected by the monsoon from the Gulf of California, occasionally bringing rare rainstorms. Most of California has a Mediterranean climate, which sometimes causes heavy rain from June 10 to April of the following year, while it hardly rains in other months. It rains all the year round in the northwest near the Pacific Ocean, but it rains the most in winter and spring. The western mountainous area absorbs enough water, and the rainfall and snowfall are quite heavy. Cascade Mountain is one of the places with the largest snowfall in the world, but there is not much snowfall in the coastal areas with low altitude.
