Equatorial Kelvin Waves and Corresponding Tracer Oscillations in the Lower Stratosphere as seen in LIMS Data

摘要: We have analyzed data from the Limb Infrared Monitor of Stratosphere (LIMS) instrument on board Nimbus 7 to investigate equatorial Kelvin waves and dynamically wave-induced variations in tracer fields such as ozone water vapor lower stratosphere. Temperature anomalies zonal wavenumber one, progressing eastward having a period 12-15 days, are clearly observed below hPa for April May 1979. Vertical phase structure with wavelength about 15 km progresses downward flow being -16 ms -1 averaged 50 10 hPa. At same time, disturbances field due observed: amplitude is maximum at 30 where vertical gradient mean largest longitudinal in-phase that temperature. These features good agreement linear wave theory. In field, hPa, we also detected one temperature though spatial not clear field.
