Section 1

• Differentiate between climate and weather
Climate: Long term (~30 years) average weather condition. Usually based off temperature, precipitation and sometimes wind.
Weather: Sunlight and precipitation over short term, sometimes daily, conditions.
• Describe the components of net radiation and how/why they vary in time and space
Net Radiation: Balance of incoming (atmosphere) and outgoing (terrestrial) solar radiation, which can vary with latitude, season, time of day, slope and aspect. All longwave radiation is a function of temperature.
• Explain causes and mechanisms of global circulation
Global Circulation: The result of an energy (net radiation) being unbalanced. It is higher at the equator and lower at the poles (moves from high-low). The Hadley Cells are an example of this
• Describe how/why temperature and precipitation vary over time and space
Temperature and Precipitation how/why vary over time and space: Temperature mimics the pattern of net radiation, but lags behind. It is affected by proximity to the ocean (wet areas to ocean have more constant temperature). Water has a high heat capacity. Aledo affects temperature.
?Temperature is: Affected by energy, elevation, continental vs. maritime location, land surface type.
?Precipitation is: Affected by rising vs. descending air masses, continental vs. maritime source of air mass.
• Why is rising air sometimes associated with formation of precipitation?
Rising Air associated with formation of Precipitation: Warm air can hold water vapor resulting in high humidity. Air rises, condensing into clouds is the primary driver of precipitation.
• Why is descending air often associated with deserts?
Descending Air associated with Deserts: As air descends towards the earth it gets warmer and creates deserts.
Oceans = wet, continents = dry
