i. Ground-based radar used by the meteorological service to supplement its knowledge of current conditions, varying from thunderstorm to upper-wind locations.
ii. A primary airborne radar designed to locate turbulent clouds within a wide area ahead of the aircraft to discriminate between safe and potentially turbulent areas in cloud formations. It provides a pictorial representation of turbulent and dangerous clouds located along the flight path and warns the pilot well in advance. The secondary function of the radar is to aid navigation by using the map-painting mode and avoiding high ground. Airborne weather radars operate in the SHF (superhigh frequency) band, whose wavelength lies between 10 and 3 cm.
