Final answer:
The standard atmosphere temperature is 15 degrees Celsius at sea level, and it decreases with height. The lapse rate is 6.5 degrees Celsius per kilometer. The troposphere is the lowest layer of the atmosphere.
Step-by-step explanation:
The standard atmosphere temperature is 15 degrees Celsius (59 degrees Fahrenheit) at sea level. However, as you go higher in the atmosphere, the temperature decreases. The rate at which the temperature decreases with height is known as the lapse rate. In the standard atmosphere, the lapse rate is 6.5 degrees Celsius per kilometer.
The troposphere is the lowest layer of the atmosphere and is where weather occurs. It extends from the surface of the Earth up to a height of approximately 11 kilometers (7 miles). The tropopause is the boundary between the troposphere and the layer above it, known as the stratosphere.
High-level charts, also known as upper-level charts, are produced for the upper levels of the atmosphere. These charts show the weather conditions and atmospheric variables in the upper part of the troposphere and into the stratosphere. High-level charts are used by meteorologists and aviation professionals to analyze and forecast weather patterns and make decisions regarding flight routes and altitudes.
