What is standard altitude gradiant?

The standard altitude gradient is the rate at which altitude increases with distance traveled horizontally. It is typically expressed in feet per mile or meters per kilometer. This gradient is used in aviation and other industries to determine the slope of terrain and obstacles in relation to aircraft flight paths.

The standard altitude gradient is the rate at which temperature decreases with increasing altitude in the atmosphere. It is approximately 6.5 °C per 1000 meters (or 3.5 °F per 1000 feet). This means that the temperature of the air decreases by about 6.5 °C for every 1000 meters that you climb in altitude.

The standard altitude gradient is caused by the fact that the air in the atmosphere is heated by the sun's radiation. The air near the ground is heated more than the air at higher altitudes, because the air near the ground is closer to the source of heat. As the air rises, it expands and cools. This cooling causes the air to become less dense, and it rises further. The cooler air at higher altitudes then creates a pressure gradient, which causes wind to blow from areas of high pressure (near the ground) to areas of low pressure (at higher altitudes).

The standard altitude gradient is a useful concept for understanding the way that the atmosphere works. It can be used to explain why the air is cooler at higher altitudes, and why wind blows in the direction that it does.
