Exam 1 Study Guide Ch.1 The early atmosphere was made up of mostly Hydrogen and Helium (4.6 billion years ago) The Average Lapse Rate is 6.5 C/1,000 m in elevation Weather – is right now – the condition of atmosphere at particular time and place Climate – past/future – specified interval of time or “average temperature” Aristotle was credited for the beginning of meteorology with the thermometer being one of the first instruments used. Wind Direction – direction in which the wind is blowing FROM Ch. 2 Internal Energy – total amount of thermal and kinetic energy All things emit radiation Wein’s Law ~max = constant/T – max wavelength in micrometers at which max radiations occur. T – object’s temp. in Kelvin. Constant: 2897 umK (use 3000) Earth emits most energy at Longer wavelengths called Longwave Radiation. The Sun emits most energy at shorter wavelengths called Shortwave Radiation. Visible light .4 -.7 micromemters Wavelengths <.4 um: Ultraviolet Wavelengths >.4 um: infrared Albedo - % of radiation returning from a surface compared to that which strikes it (reflectivity of surface) snow-high, forest-low Ch. 3 Coolest time of day – is just before sunrise June 21 – summer solstice – sun directly over N. Hemis. @tropic of Cancer Sept. 22 – Autumn Equinox – first day of fall – over equator – day and night equal Dec. 21 – winter solstice – sun over S. Hemis. @tropif of Capricorn March 20 – vernal Equinox – “spring” – noonday sun directly over equator At any time, 50% of the Earth is covered in sunlight At north pole in winter, 0% of it is covered in sunlight If you cross the equator, does the toilet bowl water flow in opposite direction. NO. Warmest part of the day is NOT high noon – because of sunlight Lag, about 5pm Be able to dram vertical profile above asphalt surface with height as y axis, and temperature as x axis. Windy vs. Calm afternoons. (windy is linear , Calm exponential) (both are decreasing). Heating degree days – estimates energy needs IF DROPPED BELOW 65F Cooling degree days – estimates energy needs IF EXCEEDS 65F Growing degree days – used by farmers; mean daily temp. 1 degree above base temp required for crop growing. Layers of the Atmoshere – be able to draw graph of these layers in relation to altitude and temperature. (Should look like a big “E” on graph) Troposphere Tropopause Mesosphere Mesopause Thermosphere
