Rainband and symmetric instability
Applying wave-CISK in a set of linearized equations, Sun (1978) obtained two different modes of the cloud bands: the band with small clouds aligns parallel to the wind shear; the other with larger clouds aligns perpendicular to wind shear, which may explain the coexistence of two cloud bands observed by Malkus and Rielh (1964) near a trough in the easterlies. Sun and Orlanski (1981a, b) proposed and proved that the two-day waves near equatorial regions can be excited by diurnal oscillation of the land sea breeze. Sun (1995) proved that the horizontal-component of the earth rotation (2Ω cos Φ) can increase or decrease the growth rate of symmetric instability in the lower latitudes. Because of 2Ω cos Φ, the x-component wind can force the cold air to ascend and warm air to descend, which is different from the conventional symmetric instability.
