MeteorologyThe difference between meteorology and climatology....
Weather (Meteorology) is the study of the state of the atmosphere ant a given time and place.
Climate (Climatology) is based on accumulated observations over time.

The Science of Geography ...
How does meteorology fit into the discipline?
First we have to define geography
How big is the Universe?Hubble Deep Field Viewhttp://hubblesite.org/newscenter/newsdesk/archive/releases/2004/07/image/aThe Hubble Telescope was pointed at a dark part of the skyLocated in the constellation Fornax, the region is so empty that only a handful of stars within the Milky Way galaxy can be seen in the image.http://micro.magnet.fsu.edu/primer/java/scienceopticsu/powersof10/
The Great galaxy in Andromeda a spiral galaxy similar to our own
Our sun is but one single middle sized and middle aged star hanging out along the edge of an average sized galaxy
Our Sun, the source of life on Earth is but one of millions.X-ray image from Dec. 2002
Our Earth is planet # 3 in a system of Nine Planets
Comparative orbits of the local solar system. Between the orbits of Mars and Jupiter is a broad band of material, the asteroid belt.
Images of the inner planets relative sizes are shown.The image of Venus is from a RADAR mapping mission as the Venusian surface cannot be seen through the thick atmosphere.
Comparatively, we are dealing with a very small part of a very big system..
The atmosphere behaves like a fluid, with currents and eddies.
Weather is a product of these atmospheric movements.
The Atmosphere of the Earth is only about 20 miles thick.
Were the Planet the size of a peach the lower atmosphere (3 miles) would be thinner than the fuzz of that peach.
The Earth's atmosphere is 77% nitrogen, 21% oxygen, with traces of argon, carbon dioxide and water.
The lower atmosphere is where life is possible and where weather occurs.
Hydrosphere:71 Percent of the Earth's surface is covered with water. Earth is the only planet on which water can exist in liquid form on the surface.
Vegetation of the conterminous United States as shown in a false color infra-red (healthy vegetation is shown in shades of red) AVHRR composite.
So here we have our Earth, fundamentally the only planet we have exploredGEOGRAPHY Is the science of describing this planet literally,Writing about Earth
From the Greek Languagegeo = Earthgraphia = description or depictionEratosthenes, a 3rd century B.C. Greek Scholar and chief librarian at the famous Library of Alexandria was perhaps the first person to use the term Geography.
What is Geography?A science that deals with the natural features of the earth and the climate, products and inhabitants. The Merriam-Webster Dictionary. Springfield: Merriam-Webster, 1997. 318
DEFINITIONSThe world and all that is in it.Spatial perspective on people, places and environment.Geography is a social science that focuses on the spatial distribution of human and physical phenomena.The science and art of understanding the spatial relations among people, place, and environment.Geography is the study of pattern and processes associated with the Earth. The focus of the geographer is on spatial patterns and how phenomena that share common space interact spatially.

DEFINITIONGeography is the study of people, places and environments. But more than that, it is a way of looking at the world and asking why it works ( or doesnt work ) and the way it does work. It is more than where, but why there. It is looking at issues from a spatial perspective and inquiring about them.
Why What is Where?andWho Cares?
The driving force for weather and oceanic currents is a thermal imbalance it is hot (due to near vertical insolation) between the tropics and cold due to reduced insolation (high angle, or in the shadows) this thermal imbalance drives all weather, which is simply seeking a balance
Heat Builds near the equatorLittle or no solar NRG is received at the polesLittle or no solar NRG is received at the poles
MeteorologyWe will investigate:the causes of weatherThe driving forces behind weather events The impacts of weather on human societyHow weather patterns occurThe tools used to measure and predict weatherHow to forecast the weather
Extreme weather events....Normal, but worthy of special study....tornadoes, blizzards, heat waves, cyclones etc....
