CHAPTER 26 WEATHER THIS CHAPTER WILL HELP YOU UNDERSTAND: • The elements of weather • The greenhouse effect • How Earth is warmed from above and below • Solar radiation and Earth's seasons • Structure and composition of the atmosphere • Why air is more dense at sea level than at higher elevations • Why the winds blow • Ocean currents and their influences • Cyclones WEATHER AND CLIMATE • Weather is the state of the atmosphere at a particular time and place. • Climate is the general pattern of weather that occurs in a region over a period of years. • Weather is short term; climate is long term. WEATHER AND CLIMATE • The six weather elements are: • Atmospheric pressure • Temperature • Wind • Precipitation • Cloudiness • Humidity CLIMATE AND LATITUDE • The world is divided into different climate zones. Temperatures are • highest in the tropics, near the equator. • lower nearer the poles. • moderate and variable in the temperate zone. SOLAR RADIATION • The Sun warms Earth's ground, and the ground, in turn, warms Earth's atmosphere. • Earth's temperature varies according to the solar intensity— the amount of solar radiation per area. • Where solar intensity is higher, temperatures are higher. GLOBAL CLIMATE CHANGE • There have been many different climatic transitions over geologic time. • Today, Earth is experiencing a warming trend— apparently from human activities: "anthropogenic" climate change. • The greenhouse effect is the warming of the atmo
