Unformatted text preview: Outline Further Reading: Chapter 05 of the text book- continental vs. marine regimes- temperature structure of the atmosphere- seasonal variations Natural Environments: The Atmosphere GE 101 Spring 2011 Boston University Myneni Lecture 11:Temperature-Regimes-02 Feb-14-11 (1 of 14)- urban heat island Introduction Natural Environments: The Atmosphere GE 101 Spring 2011 Boston University Myneni Lecture 11:Temperature-Regimes-02 Feb-14-11 (2 of 14) Previously , we discussed diurnal and seasonal temperature variations based solely on insolation and latitude In this lecture , we shall consider other factors ( surface type, coastal vs continental location and elevation ) to further understand large scale temperature variations Need to understand: Differences in how radiation interacts with different types of matter, specifically water and land Oceans Natural Environments: The Atmosphere GE 101 Spring 2011 Boston University Myneni Lecture 11:Temperature-Regimes-02 Feb-14-11 (3 of 14) High specific heat - can absorb lots of energy w/o much change in temperature (The specific heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius - specific heat of water is 1 calorie/gram C). It s a fluid -> it can absorb heat at the surface and mix it down into the deeper ocean Solar radiation can penetrate past the surface down to approximately 10m Most excess energy transformed into latent heat -> does not involve a change in temperature For oceans, all four result in small, slow changes in temperature -> Land Natural Environments: The Atmosphere GE 101 Spring 2011 Boston University Myneni Lecture 11:Temperature-Regimes-02 Feb-14-11 (4 of 14) Low specific heat does not require much energy to change its temperature It s a solid -> can t mix energy to lower levels so it all stays at the surface Solar energy can t penetrate past the surface -> heat only the surface layers Less excess energy is transformed into latent heat and more into sensible heat,...
