PRESENTATION OUTLINE
Climate example:
reference to typical conditions and a value of typical rainfall.as well as the things that cause climates such as changes in volcanic activity, solar output, and the Earth's orbit around the Sun.

CLIMATE RESEARCH
Atmosphere
Definition:the mass of air that surrounds the earth above its surface the gaseous envelope (air) surrounding the earth to a height of c. 1,000 km (c. 621 mi): it is c. 21% oxygen, 78% nitrogen, and 1% other gases, and rotates with the earth, because of gravity

If we didn't have the atmosphere toxic and harmful gasses from the sun would harm us and we could die as well as it blocks some of the suns more harmful rays. Thus effecting the weather and temperature.

AIR PRESSURE/barometric pressure
is the force per unit area exerted on a surface by the weight of air above that surface in the atmosphere of Earth

Air pressure example:
Altitude affects the temperature of the air because air pressure gets lower as the altitude increases. The higher the pressure of any gas -- like our air, for example -- the warmer it becomes.

Another air pressure example:
The higher the temperature of the air, the faster it rises and loses density, decreasing the barometric pressure. The cooler it is, the denser the air becomes. This causes the barometric pressure to rise. Hotter temperatures generally mean lower pressure.

Wind pressure
Wind results from a horizontal difference in air pressure and since the sun heats different parts of the Earth differently, causing pressure differences, the Sun is the driving force for most winds.
Also different air masses influence the precipitation and weather patterns
A high pressure area:is an area where the atmospheric pressure is greater than that of the surrounding area. In some places highs are referred to as anticyclones.
Low pressure area:is an area where the atmospheric pressure is lower than that of the area surrounding it. Lows are usually associated with high winds, warm air, and atmospheric lifting. Because of this, lows normally produce clouds, precipitation, and other bad weather such as tropical storms and cyclones.

Clouds
Water droplets or ice particles floating in the atmosphere.

Cloud examples:
Causes fronts is defined as the leading edge of a cooler mass of air, replacing (at ground level) a warmer mass of air, which lies within a fairly sharp surface trough of low pressure. It forms in the wake of an extratropical cyclone, at the leading edge of its cold air advection pattern, which is also known as the cyclone's dry conveyor belt circulation. Temperature changes across the boundary can exceed 30 °C (54 °F).[1] When enough moisture is present, rain can occur along the boundary.A warm front is defined as the transition zone where a warm air mass is replacing a cold air mass. Warm fronts generally move from southwest to northeast and the air behind a warm front is warmer and more moist than the air ahead of it.

Precipitation
Water as a liquid or solid that falls to earth

Precipitation example:
Produces snow hail rain & sleet also fronts effects this by the cold fronts are moving masses of cool air. Warm air has the capacity to hold more moisture in it as water vapor. When the moving mass of cold air comes in contact with warmer air it causes the warmer are to flow over them. As the warm air containing more moisture rises it is then cooled, and because it can now hold less water, the moisture it holds precipitates out causing precipitation in the form of rain, snow, hail, fog, etc.

Weather maps
DISPLAYS VARIOUS METEOROLOGICAL FEATURES ACROSS A PARTICULAR AREA AT A PARTICULAR POINT IN TIME AND HAS VARIOUS SYMBOLS WHICH ALL HAVE SPECIFIC MEANINGS.

Weather map example:
This helps meteorologists see before hand what weather conditions are for that area as well as seeing forecasts and collecting data.

Water cycle example:
It shows where the water goes as well as where it is stored underground or above ground and it effects the wind currents as well as condensation like dew. Also has the effect of evaporation with run off water.

Groundwater example:Water is recharged to the groundwater system by percolation of water from precipitation and then flows to the stream through the groundwater system.
Water pumped from the groundwater system causes the water table to lower and alters the direction of groundwater movement.
