Weather Quiz

Thermals are updrafts in convective currents dependent on solar heating. A temperature inversion would result in stable air with very little, if any, convective activity.

Between 1000Z and 1200Z, the visibility at KMEM is forecast to be 3 statute miles (BECMG 1012... 3SM).

Local conditions, geological features, and other anomalies can change the wind direction and speed close to the Earth's surface, making it difficult to control and maneuver the sUAS.

Part 107 require the minimum distance of the sUAS from clouds must be no less than 500 feet below the cloud. The towers depicted 4 NM east of K36 are 292 feet AGL. 292 + 500 = 792 feet AGL.

Advection fog forms when moist air moves over colder ground or water. It is most common along coastal areas. This fog frequently forms offshore as a result of cold water, then is carried inland by the wind.
