Global and Local Winds in China

     China's latitude max is an estimate of 53.45 N and a min of 18.33 N. China's longitude max is about 122.6 E and min of 73.99 E (Google Maps). China is located in the Eastern and Northern Hemisphere  of planet Earth (World Atlas). The country of China resides in the Ferrell Cell from the "atmospheric cell". China resides in the Westerlies wind belt. The net surface flow is toward the poles and Coriolis bends them to the west. The Westerlies blow from West to East. China is located in a High pressure belt. China is not located in the horse latitude because the horse latitude is in the 25-30 N (S) and China is located in the 30-60 N (S). China is also not located in the Polar front because China is not way up north in the 60-90 N (S) region. China is also not in the Doldrum front because China is not close to the equator.

     China's climate is sporadic. Since China has a vast mountain region along with plains, valleys, desert, and coastal areas, the weather tends to be different in the same instant. One area can be rainy while another area is dry and sunny. The high mountain regions tend to be really cold at times because of the winds that pass through. Since China's latitude begins at the border of 30 N, it contains the region of a desert due to the subsidizing air associated with the Hadley Cell. The wind in this region is moving from West to East along with some trade winds in the South of China that are going East to West.

     China has big mountain ranges that occupy two-thirds of the country. There are about 26 mountains in Tibet, China. Mount. Everest, Mount. Cho Oyu, Mount Shisha Pangma are 3 of the tallest mountains in the region (Summit Post). Mountain breezes, valley breezes, Chinooks, Katabatic winds, and Monsoons are all types of breezes or winds that are associated with mountains.
China has the possibility of experiencing each and every wind listed above because of the vast majority of mountain ranges making up most of the country. China has the famous Jiuzahaigou Valley which covers 230 square miles (Travel China Guide). China has a variety of land regions which allows breezes and wind systems like monsoons possible. Monsoons are actually significant in the fertilization of the soil because it has been able to produce a lot of food for the people (Owl and Mouse). China has a coastline of 14,500 km in length (World by Map). Sea breezes and monsoons are two breezes associated with coastlines. China has the possibility of experiencing these breezes because it has a big coastline in which the breezes can move in through and even though some of the monsoons pass through the Indian ocean and then through the Himalayan mountains, it still reaches China.

Temperature Controls in the city of Beijing in China

      The capital city of China is Beijing. The latitude of the city of Beijing is 39.9139° N and the longitude is 116.3917°E. The warmest month in Beijing is July with an average monthly temperature of 81°F. The coldest month in Beijing is January with an average of 25°F. Based on the information above, the annual range of temperature for my city is 87.8°F.
      The altitude of the land has an effect on the temperatures. The land in China varies from low altitudes to very high altitudes of 3.3 meters to above 5500 meters (China Highlights). The city of Beijing is located in the Northern part of China with an altitude of 44 meters (China Highlights). The city of Beijing has a variety of weather temperatures as the seasons change. During the winter the atmosphere keeps Beijing colder with some snow and during the summer, the atmosphere keeps Beijing very hot. Ocean currents are something that do not have an effect on the control of temperature. China is already cozy between Mongolia, India, Myanmar, and other countries so most of the land is being bordered by land and not ocean waters. Beijing is about 2 hours west away from the ocean.
      The pollution levels in China have been going up each year and records show that the smog in the major cities of China has been barely making it suitable to live in (Deutsche Welle).  The air pollution has been rising to the maximum of 14 times the maximum level which could play a part in warming up the atmosphere and causing the annual temperatures to increase (Deutsche Welle). As the temperature increases there will be many plants and animals that will not know how to adapt very well. When the water of the ocean heats up year by year, it causes it to make stronger hurricanes and could potentially reach the city of Beijing. With the pollution increasing it could lead to drought which would affect not only Beijing but China in a whole.
