An aircraft flying through dry convection is commonly exposed to turbulence intensities in what range?

Light to moderate

Which tool continuously monitors surface winds at remote sites around the airport and communicates the information to a central computer?

Low-level wind shear alert systems

Which of the following is characterized by a strong core of cool, dense air descending from the base of a convective cloud?

Microburst

Critical wind shear for aircraft operations generally occurs where?

Over horizontal distances of one nautical mile or less and vertical distances of less than 1,000 feet

If occupants of an aircraft are forced violently against seat belts or shoulder straps, unsecured objects are tossed about, and food service is impossible, what is the level of turbulence intensity?

Severe

How is wind shear affected as the horizontal temperature gradient across the frontal zone gets stronger?
