Dry Climates (Group B) 7. Describe the general location, temperature characteristics, precipitation characteristics, and main controls of the following climates. You should be able to recognize these climates from a climograph: BWh Subtropical desert lie in or very near the band of the subtropical highs. Three adjectives describe the precipitation in subtropical desert: scarce, unreliable, and intense. Temperatures in BWh regions are also distinctive. The combination of low-latitude location and lack of cloudiness permits a great deal of insolation to reach the surface. In summer the average is 30s°C and in mindwinters months have an average temperatures in the high teens °C. BWk Midlatitude desert occur primarily in the deep interiors of continents. Precipitation in mmidlatitudes desert is much like that of subtropical deserts – meager and erratic. Mid-latitudes deserts develop in the band of the westerlies in locations either far removed geographically from the ocean or in the rain shadows of mountain ranges. 8. What is the general difference between a desert climate and a steppe climate? Deserts are extremely arid, whereas steppes are semiarid. Most deserts are large core areas of aridity surrounded by a transitional fringe of steppe that is slightly less dry. 9. What are the main differences in controls of BWh (subtropical desert) and BWk (midlatitude desert) climates? The primarily climatic differences between mid-latitude and subtropical deserts are in temperature, especially winter temperature. BWk regions have severely cold winters. Mild Midlatitude Climates (Group C) 10. Describe the general location, temperature characteristics, precipitation characteristics, and main controls of the following climates. You should be able to recognize these climates from a climograph: Cs Mediterranean Cs climates are found in five parts of the world on the western side of continents centered at about 35°N and 35°S. The Cs climates have three characteristics: 1. The modest annual precipitation falls in winter; summers are virtually rainless. 2. Winter temperatures are usually mild for the mid-latitudes, and summers vary from warm to hot. 3. Clear skies and abundant sunshine are typical, especially in summer. In summer these regions are dominated by dry and in winter the wind and pressure belts shift equatorward. Cfa Humid subtropical are found on the eastern side, centered at about the same latitude. Summer temperatures are generally warm to hot. Precipitation tends to have a summer maximum; winter is a time of diminished precipitation. Winter temperatures in Cfa are mild but little cooler than in Mediterranean regions. Cfb Marine west coast are situated on the western side of continents between about 40° and 60° N and S. Prolonged summer heat waves are rare, and winter frost are relatively infrequent. The dominant climate control for these regions is the year-round cool maritime influence brought by the onshore flow of the westerlies.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
