31Potential temperature — The potential temperature of a parcel of fluid at pressure P is the temperature that the parcel would acquire if adiabatically brought to a standard reference pressure P {0}, usually 1000 millibars. The potential temperature is denoted heta and,… …
32Radio acoustic sounding system — A radio acoustic sounding system (RASS) is a system for measuring the atmospheric lapse rate using backscattering of radio waves from an acoustic wave front to measure the speed of sound at various heights above the ground. This is possible… …
33Lifted index — The lifted index (LI) is the temperature difference between an air parcel lifted adiabatically Tp(p) and the temperature of the environment Te(p) at a given pressure height in the troposphere (lowest layer where most weather occurs) of the… …

35Microbarom — In acoustics, microbaroms, also known as the voice of the sea ,[1][2] are a class of atmospheric infrasonic waves generated in marine storms[3][4] by a non linear interaction of ocean surface waves with the atmosphere …
36Lake-effect snow — Lake Effect redirects here. For the American literary journal, see Lake Effect (journal). Lake effect precipitation coming off Lake Erie and into Western New York, as seen by NEXRAD radar, October 12–13, 2006 …
37Cloud feedback — is the coupling between cloudiness and surface air temperature in which a change in radiative forcing perturbs the surface air temperature, leading to a change in clouds, which could then amplify or diminish the initial temperature perturbation.… …
