Defining Climate


-Study of Earth's climate and the factors that cause past, present, and future climatic changes

-Climate describes the long term weather patterns of an area

-Climate variations of temperature, precipitation, wind, and other weather variables


-Normal are the areas standard values

-Normal dates are temperatures, rainfall, wind speed and direction, humidity, and air pressure

-Normal are measure monthly for about 30 years

Limitations of Normals

-Weather condition on any given day might differ widely from normal

-Normal temperatures may never be the given normal of the area

-Climate is to region, while normal are for a specific place where the meteorological data is collected

Cause of Climate

-Differences in latitude, topography, lakes and oceans, moisture, global wind patterns, ocean currents, and air masses


-Earth's tilt and latitude vary on how much sunlight and heat an area gets

-Some places on earth are very cold and frigid due to the latitude they are at while some are very warm and humid

-Some places have a lot of rainfall while some are very dry due to droughts

Topographic Affects

-Water heats up and cools down more slowly than land

-many coastal regions are cooler in the winter than they are in the summer

- Inland areas have similar latitudes

Air Masses

-Two of the main causes of weather are the movement and interaction of air masses

- Air masses also affect climate

-Air masses have a distinct origin cause by primarily by differences in the amount of solar radiation
