The atmosphere has 4 layers: the troposphere that we live in near the surface of the earth; the stratosphere that houses the ozone layer; the mesosphere, a colder and lower density layer with about 0. Why do I care? The structure of the atmosphere dictates the way the atmosphere behaves and controls how weather develops near the surface of the earth. The atmosphere consists of 4 layers: the troposphere, stratosphere, mesosphere, and thermosphere.

Chicago lies midway between the Continental Divide and the Atlantic Ocean, and is miles north of the Gulf of Mexico. Chicago's climate is typically continental with cold winters, warm summers, and frequent short fluctuations in temperature, humidity, cloudiness, and wind direction. Many consider the more moderate temperatures of spring and fall to be the most pleasant. Lake Michigan provides a moderating influence on temperature while boosting the amount of snowfall received in the city. Four factors control the continental climate of Chicago: 1 the sun, 2 weather systems, 3 urban areas, and 4 Lake Michigan.
By Stanley Changnon. Weather refers to the state of the atmosphere and includes temperature, precipitation, humidity, cloudiness, visibility, pressure, and winds. Weather, as opposed to climate, includes the short-term variations of the atmosphere, ranging from minutes to months. Climate is typically considered the weather that characterizes a particular region over time. The weather must be measured and records kept to gain an understanding of the forces at work and to yield the information on the averages and extremes. By studying weather records, atmospheric scientists may be able to predict the weather ahead on scales of weeks to months with greater accuracy and modify more successfully the weather to increase precipitation or ameliorate severe storms.

Weather is the condition of the atmosphere at a particular place over a short period of time, whereas climate refers to the weather pattern, using statistical data, of a place over a long enough period to yield meaningful averages. Climate is an important element because it indicates the atmospheric condition of heat, moisture and circulation; it plays a dominant role in shaping vegetation and soil; and it ultimately affects all forms of life, as a result of the very definition of the word, which is a scientific prediction, based on evidentiary statistics, sustained over a long period. There are many elements that make up both the weather and the climate of a geographical location. The most significant of these elements are temperature , atmospheric pressure , wind , solar irradiance , humidity , precipitation , condensation and topography.
Atmospheric physics Atmospheric dynamics category. Climate category Climate change category. Climate is the long-term average of weather, typically averaged over a period of 30 years.
Although almost anything can happen with the weather, climate is more predictable. Climate then is the long-term average of weather. Good climate is why we choose to vacation in Hawaii in February, even though the weather is not guaranteed to be good!
All EGU highlight articles. Around the world each year, extreme precipitation events cause catastrophic flooding that results in tragic loss of life and costly damage to infrastructure and property. However, a variety of different weather systems can cause these extreme events, so a detailed understanding of the atmospheric processes that lead to their formation is crucial.
