What is convective in aviation weather?
Convective weather is the vertical transport of heat and moisture in unstable environment, which is real technically speaking, basically a thunderstorm or developing clouds, such as towering cumulus.
What is air traffic capacity?
The capacity for an Air Traffic Management System is its ability to provide Air navigation Services to a certain volume of air traffic, in line with the targeted high level of safety and without imposing significant operational, economic or environmental penalties under normal circumstances2.
What are the four categories of aviation weather?
There are four types of weather observations: surface, upper air, radar, and satellite. Surface aviation weather observations (METARs) are a compilation of elements of the current weather at individual ground stations across the United States.
What are three aviation hazards that can be associated with convective precipitation?
Hazards associated with convective weather include thunderstorms with severe turbulence, intense up- and downdrafts, lightning, hail, heavy precipitation, icing, wind shear, microbursts, strong low-level winds, and tornadoes.
How does convection affect aircraft?
On the surface convection is not innately harmful, in fact necessary for life itself. But when mixed with moisture and the right thermal conditions, it brings lightning and turbulence that can bring havoc to any airspace.
What is convective wind?
Hence, convective winds here refer to all winds—up, down, or horizontal— that have their principal origin in local temperature differences. This is somewhat different from common meteorological usage, wherein convection implies upward motion only.
What is airport capacity?
38 Airport capacity is a measure of the maximum number of aircraft operations that can be accommodated on the air- port or by an airport component within a given period of time. The context of this report is airside or runway capacity.
What does a convective outlook AC describe for a following 24 hour period?
It provides prospects of both general and severe thunderstorm activity during the following 24 hours. What does a convective outlook (AC) describe for a following 24 hour period? Areas of slight, moderate, or high risk of severe thunderstorms.
What is the purpose of a convective outlook forecast?
A convective outlook is an advanced meteorological term that refers to the predicted severity and path of a storm. A convective outlook forecasts a combination of factors: the severity of the storm, the timing of the threat, and the expected path of the severe weather system.
What is convective turbulence?
Thunderstorms are convective clouds, which means they are driven by the buoyancy of warm rising air inside the cloud. Turbulence is the name for random gusty fluctuations (vertical and horizontal) of the wind.
What altitude will convective air currents cause turbulence?
Maximum turbulence usually occurs near the mid-level of the storm, between 12,000 and 20,000 feet and is most severe in clouds of the greatest vertical development.
