Climate Verses Weather Is there a difference?

Climate Vs. Weather Climate Long-term weather patterns of an area Current state of the troposphere Short term variations

Climatology The study of Earth’s climate and the factors that affect past, present, and future climatic changes

Normals Standard values for a location Average values over a long period of time

Longitude and Latitude Lines:

What Causes Different Climates? Topography Coastal Regions, areas near water, are warmer in the winter and cooler in the summer Latitude

Latitude The latitude lines are all parallel lines running east to west and they are numbered from 0 to 90 degrees increasing from the equator to the North Pole (0 to -90 degrees towards the South Pole). You cannot see latitude lines on the ground. They are just a way of measuring how far north or south of the equator something is on a map or globe model.

Arctic Circle Tropic of Cancer Equator Tropic of Capricorn Latitude Equator Tropic of Capricorn Tropic of Cancer Arctic Circle Antarctic Circle 66.5° N 23.5° N 23.5° S 66.5° S 0°

Latitude Polar Temperate Tropics Tropics Temperate Polar

Climate Regions Tropics Temperate Polar Most solar radiation, generally warm Between Tropics of Capricorn and Cancer Temperate Between 23.5 and 66.5 North and South Mild temperatures Polar 66.5 North and South to the Poles Cold Temperatures

Koeppen Classification System Classified based on temperature and amount of precipitation Tropical Dry Mild Continental Polar

Climate Change

Long-Term Climatic Change Climates change over extremely long periods of time Ice Ages – Periods of extensive glacial coverage Most recent ended 10,000 years ago Temps dropped 5°C

Short-Term Climatic Change Caused by regular variations in daylight, temp, and weather patterns Examples: Seasons El Nino (Warm ocean current)
