Geography 1111 Lecture 17 Notes Climate Controls: o Latitude o Land/Water Heating Differences o Geographic Position and Prevailing Winds o Mountains and Highlands o Ocean Currents o Global Pressure and Wind Patterns Climatic Variables: o The daily, monthly and annual averages (means) are calculated using a 30 year period of data The current averages use the period 1980 – 2010 o Average daily maximum and minimum temperature Mean monthly temperature = average temperature for a month Mean annual temperature = average temperature for a year Mean monthly precipitation = total precipitation for the month Mean annual precipitation = average total precipitation/year Köppen Classification Scheme: o Developed by Wladimir Köppen (Koeppen) and is the most widely used system over the past 120 years o It was originally based on patterns of vegetation and how those plant associations were associated with patterns of temperature and precipitation o Köppen system is a series of letters for temperature, precipitation values, and seasonal changes o It comprises 5 principal groups with 4 based on temperature, and 1 based on precipitation o First letter: upper-case letter and temperature based: A: warmest climates B: precipitation based C, D, and E: coldest climates o Second letter: may be an upper-case or lower-case letter For A, C, D climates a lower-case letter is used and this refers to the seasonality of precipitation ***know the lower case letters*** f: no distinct dry season m: monsoon s: distinct dry season in summer (wet winter) w: distinct dry season in winter (wet summer) For B climates the second letter is upper-case and refers to the severity of drought (upper case S or W) For E climates the second letter is upper-case and refers to the severity of cold (upper case F or T) o Third letter: For A and E climates there is none For B, C, D climates it refers to warmest or coldest temperatures Climographs: o Also known as climate diagrams or climate graphs are a graphical representation of a locations average monthly temperature and precipitation o It can reveal temperature range, seasonality of temperature and precipitation o May include the locations latitude and longitude, sometimes the climate type and elevation
