3、ormation given in the passage.Types of ClimateClimate is the combination of temperature, moisture, wind, and sunshine at a place over a period of many years. Weather is made up of atmospheric conditions during a few hours or days. The weather may be rainy on a certain day. But that place may usually
4、 have a warm, dry, sunny climate. We learn about the climate of a place by studying its temperature, moisture, wind, and sunshine from season to season and year to year.Temperature and the amount of rainfall are the two most important elements of climate. Others are humidity (air moisture), cloudine
5、ss, fog, sunshine, wind, storms, and air pressure.There are many different types of climate on earth. Climates of the world can be classified according to their latitudes and the plants that grow there. Different kinds of plants need different amounts of heat and moisture for growth. The vegetation
6、of a region tells us about temperature and rainfall conditions over a long period of time.Tropical ClimatesTropical climates are found in regions between 35N and 35S latitude. In the tropical rain forest (nearest the equator) conditions are warm and rainy all year long, and there is a thick cover of
7、 trees. Places farther north and south of the equator have a tropical wet-and-dry climate. There the forests are not so dense, and many trees lose their leaves in the dry season. Along 23.5N and 23.5S latitude there are vast regions of tropical desert climate, where very little vegetation can grow.
8、Subtropical ClimatesSubtropical climates are usually found between 30 and 40 North and South latitudes. The subtropical western coasts of the continents have a Mediterranean climate. Summers are hot and dry; winters are mild and wet. On the subtropical eastern coasts of continents the climate is hum
9、id subtropical. Summers are hot, and winters are mild. There is enough rainfall in all seasons for forests.Mid-latitude ClimateMid-latitude climates occur between 40 and 60 NS latitudes. Strong westerly winds blow in the mid-latitudes. The climate of the west coast of North America is mild and rainy
10、 most of the year. It helps the growth of fine timber forests. Some places in the mid-latitudes do not receive moisture because of mountain barriers or their great distances from the oceans. Humid continental climates cover large mid-latitude area in eastern parts of the continents. They are forest
11、climates with cold winters and warm summers. Most of the rainfall comes in the summer.High-latitude ClimatesHigh-latitude climates occur from 60 to the poles, North and South. In the high latitudes temperatures are very cold in winter and cool in summer. The short summers are warm enough for forests
12、 of evergreen trees. Greenland and Antarctica have a polar climate, where great ice caps exist because of year-round freezing.High-altitude ClimatesHighland climates are cooler than the surrounding lowlands because of the effects of altitude. Highland climates are found on the high mountains of the
13、world, even on the equator. In the tropics and mid-latitudes different kinds of vegetation grow in zones up the slopes of mountains to the permanent snowfields.The Causes of Different ClimatesThe differences in the climate from place to place are caused by climate controls. The major climate control
14、s are latitude, altitude, land and water bodies, ocean currents, and storm centers.Latitudes make climates colder toward the north and south poles (high latitudes) than at the tropics near the equator (low altitudes). Low-latitude regions remain warm throughout the year. At higher latitudes there ar
15、e greater differences between winter and summer temperatures.Altitudes affects climate by lowering temperatures as the higher above sea level increases. At high altitudes the air is less dense and dose not absorb and hold as much heat. On the average, the temperature drops about 2 degrees Celsius fo
16、r each 300 meters of altitude (about 3.5 degrees Fahrenheit for each 1,000 feet). Thus snow can remain on mountain-like Fujiyama when nearby lowlands are warm.Land and water bodies influence climate. Land warms up rapidly in summer and cools off rapidly in winter. But large bodies of water change te
17、mperature slowly, with the seasons. Mid- continental places in middle and high latitudes have a continental climate. Summers are warm and winter cold. Island and seacoasts usually have milder winters and cooler summers because of the water surfaces nearby.Ocean currents affect climate in many parts
18、of the world. Some currents carry warm water to cool regions; others carry cool water to warm regions. The Labrador Current is cold. The Gulf Stream is a warm ocean current. It carries warm water from the tropical Atlantic toward the coasts of northwestern Europe. As a result, winters in the British
19、 Isles and in Western Europe are warmer than other regions in the same latitudes.Winds carry heat and moisture and therefore affect climate. Winds that come from lands in high latitudes are cold and dry. Some winds change direction with the seasons. In southern Asia winds called monsoons are dry and
20、 cool in the winter, when they blow from the land. In the summer they blow from the ocean and produce heavy rainfall. Climate and the water cycleWater enters the atmosphere by evaporation from land and water surfaces. Winds carry water vapor and clouds to other areas. There the moisture is returned
21、to the earth in the form of rain or snow. Much of the water falls on land and runs off to the sea in rivers. But some moisture enters soil. It helps growing plants or builds up the groundwater supply. The constant movement of water from land to sea to air and back again is called the water cycle. Th
22、e amount of water available for farming, industry, and many other uses differs from one climate to another. People try to overcome these differences by using water resources wisely. The water cycle can be controlled in part for a short time by storing water in reservoirs, irrigating land, draining w
23、etlands, or pumping water from wells.Climate and peopleClimate influences peoples comfort, well-being, and activities in many ways. Most people do not work as well in a hot, most climate as in a cooler, drier climate. Extremely high or low temperatures are uncomfortable. Certain diseases are more co
24、mmon in some climates than in others. It is difficult to determine what is the best or ideal climate for human beings. People differ in their reactions to climate because of their individual characteristics and attitudes.The amount and kind of clothing people wear is determined partly by climate. Cl
25、othing for cold climates gives protection against wind and cold. Less clothing is needed in warm climates. There are many types of special clothing for wind, cold, sun, rain, and snow.People build houses mainly for shelter from the climatic elements. Carefully planned houses take advantage of sunlig
26、ht, wind direction, and other factors to obtain a maximum of comfort as well as protection. The amount of heating or air conditioning needed in a building depends upon the construction of the building as well as the outside climate. Many modem inventions have made it possible for people to live comf
27、ortably in any kind of climate.Climate affects the food supply by setting limits for profitable production of crops and animals. Climate influences cattle raising and forestry because it determines where grasslands and forests will grow. Winds, clouds, and storms have to be considered in travel by l
28、and, sea, or air and even in the launching of satellite. Most industries take special attention to protect their products against weather and climate during manufacture, storage, and shipment.（分数：70.00）(1).Climate is the combination of temperature, moisture, wind and sunshine at a place over a certa
