What Makes Weather

The Changing Climate
Earth's climate is constantly changing. This occurs because of a number of factors such as volcanic eruptions, sun spots, earth's magnetic changes, or mankind's pollution of the environment.
The Weather Book
A Complete Illustrated Guide to Meteorological Phenomena, Weather Forecasting, and Climate.
A wonder of the world that should be noticed and taken seriously as the weather affects everyone everyday.
meteorology - The science dealing with the atmosphere and its phenomena , including weather and climate.
-origin 1610–20; < Greek meteōrología discussion of celestial phenomena. Pronounced meteor, -o-, -logy
weather - The state of the atmosphere at a particular time and place. Weather is described in terms of variable conditions such as temperature, humidity, wind velocity, precipitation, and barometric pressure. Weather on Earth occurs primarily in the troposphere, or lower atmosphere, and is driven by energy from the Sun and the rotation of the Earth. The average weather conditions of a region over time are used to define a region's climate.
-origin - before 900; Middle English (noun), Old English weder; cognate with Dutch weder, German Wetter, Old Norse vethr
Written by: Ralph Hardy, Peter Wright, John Kington, and John Gribbin
Long term weather patterns over a region are called climates.
Monsoon / Sub-Tropical
Steppe / Savanna
Major events can lead to a sudden rise or drop in the temperature resulting in drastic changes towars our environment.
Winds / Ocean Currents
The sun's energy runs everything on earth. The weather can be effected dramatically by the varying amount of sunlight reaching the planet at various latitudes.
The seasons occur because the earth is tilted on its axis by 23.5 degrees. The seasons alternate between the northern and southern hemispheres due to the varying angle of the sun. This is also effected by the length of days and nights.
When you add collected data for many different regions you can create a larger image giving a better look at current weather conditions. Satellites are used for finding global weather patterns and data collection.
When you combine all of the imputes of weather, the result is weather systems. They are ever-changing and constantly moving around our planet.
The different climates are classified into various types depending upon their vegetation. Climates directly effect the different cultures of the world.
Within the last couple of decades, forecasting has become more precise and easier to do with the rapidly advancing computer systems. Synoptic maps are commonly used to indicate specific conditions for any place on the globe.
