ATMOSPHERIC STRATIFICATION Meaning and
Definition
-
Atmospheric stratification refers to the layering or division of the Earth's atmosphere into distinct horizontal and vertical zones based on variations in temperature, density, and composition. It is a fundamental concept in the field of atmospheric science and climatology.
In the horizontal direction, atmospheric stratification describes the division of the atmosphere into different layers or regions, such as the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. Each layer has its own distinct characteristics, such as temperature changes, pressure gradients, and composition variations, which contribute to the overall structure and behavior of the atmosphere.
Vertical stratification, on the other hand, refers to the division of the atmosphere based on temperature changes and stability. It includes layers such as the surface boundary layer, where convection and turbulent mixing dominate, the free troposphere, where weather dynamics and moisture transport occur, and the upper atmosphere, where temperature inversions and wind patterns are prominent.
These layers and regions of atmospheric stratification play a crucial role in weather patterns, climate variations, and atmospheric circulation. They affect the distribution of heat, moisture, and gases, influencing the formation of clouds, precipitation, and global air circulation patterns. Understanding atmospheric stratification is vital for predicting weather phenomena, studying atmospheric chemistry and climate change, and comprehending how Earth's atmosphere interacts with other components of the Earth system.
Etymology of ATMOSPHERIC STRATIFICATION
The term "atmospheric stratification" is composed of two main parts: "atmospheric" and "stratification".
The term "atmospheric" is derived from the Greek word "atmos", meaning "vapor" or "steam". It was first used in English in the early 17th century to refer to the envelope of air surrounding the Earth. Over time, "atmospheric" has become widely used to describe anything related to the Earth's atmosphere.
The term "stratification" is derived from the Latin word "stratum", meaning "layer" or "stratum". It has been used in various fields to describe the arrangement or division of something into layers or strata. In the context of the Earth's atmosphere, "stratification" refers to the vertical layering or division of the atmosphere based on temperature, density, or other properties.
