Climate and Factors that Affect It Weather: the state of the atmosphere at a specific place and time on the Earth’s surface Climate : different from that of daily weather because it refers to the average values of weather elements, such as temperature and precipitation Climatology : The study of the geographic distribution and the character of the Earths climates. They study long term and precipitation patterns Meteorology: study of short term atmospheric phenomena such as thunderstorms that constitutes day to day weather in a particular place Variables Latitude 1. Two latitudinal variables critical to climate related to the Earth-Sun relationship a. Intensity of Radiation b. Length of the day -High latitude places are relatively cold (receive low amounts of insolation over the course of the year -Tropical latitudes are usually warm (insolation is intense) -Insolation has an impact on overall air temperature

Seasonality Critical variable in the distribution of global climates for two reasons related to the sun angle 1. The number of hours of sunlight in a day changes in many places over the course of a year 2. Insolation and temperature can be highly variable between the winter and summer seasons - In tropical regions, there is very little annual difference in these variables, which is reflected in the relatively consistent temperature and precipitation characteristics of tropical climates Air mass circulation The unique distribution of pressure systems results in regions with heavy or persistent precipitation, such as those associated with ITCZ while other like STH is dry. maritime/continental relationships proximity to a large body of water can have a big impact on temperature and direction of air flow -In the interior of continents the annual temperature range can fluctuate a great deal, whereas it is

moderated along ocean coasts. -large bodies of water can also be great sources of atmospheric water vapor through the process of evaporation and air flow can transport water vapor inland where it falls at precipitation -evaporation of large amounts of water vapor is usually associated with warm oceans -cold oceans have a drying effect on adjacent continental locations Topographical Effects Can dramatically influence atmospheric pressure in a region (example: windward side of a mountain is often a place of heavy precipitation because air cools adiabatically there). -All these variables interact with each other to influence climate Koppen Climate Classification Purpose: To identify certain characteristics (such as temperature and precipitation) that has definable regional patterns -Tropical regions are wet due to the ITCZ, whereas latitudes around 30 degrees N/S are dry from the STH

-this describes world climates based on average monthly temperature, average monthly precipitation, and total annual precipitation 6 Major Climate Groups A -Latitudes near the Equator -found at low latitudes that straddles the Equator extending to approximately 25 degrees N/S -climates are warm
