MLS upper-tropospheric H 2 O. Water vapor in the troposphere is an important forcing for the diurnal tide and the peak of the heating rate is near 8 km (Chapman and Lindzen, ).Here, we use MLS and hPa H 2 O as the proxy for the intensity of H 2 O radiative forcing in the troposphere to examine seasonal variations of the tidal heating due to this by: They reported that a 25% increase in stratospheric O 3 results in a 2% increase in hPa O 3 in the northern mid-latitudes, approximately half of the interannual tropospheric O 3 variability, based on CAM-Chem simulation. Variations in temperature and water vapor in the atmosphere also influence production and loss of O by:

  The upper-troposphere water vapor (UTWV) band brightness temperature (BT) dataset derived from the High-resolution Infrared Radiation Sounder (HIRS) channel 12 of the National Oceanic and Atmospheric Administration (NOAA) polar satellites from to is used to analyze the seasonal and interannual variations for the global monsoon regions. Cited by: 7. In particular, large interannual variations of water vapor in the tropical UTLMS have been observed and shown to be important for both climate and chemical reasons (e.g., Dessler et al. Interannual Variations of Stratospheric Water Vapor in MLS Observations and Climate Model Simulations Article (PDF Available) in Journal of the Atmospheric Sciences 71(11) . Observed annual and interannual variations in tropospheric water vapor Miscellaneous Gaffen, D.J. Radiosonde observations from a global network of 56 radiosonde stations for are used to describe and quantify annual and interannual variations of tropospheric water vapor.

Results indicate that the upper troposphere maintains nearly constant relative humidity for observed perturbations to ocean surface temperatures over the observed period, with increases in temperature ∼ times the changes at the surface, and corresponding increases in water vapor (specific humidity) of 10%–25% °C −1. Increases in water Cited by: feedback due to upper-tropospheric water vapor (H 2 O), whereby a change in climate state changes water vapor, which is the primary greenhouse gas (Held and Soden ). This increase in water vapor then further changes the climate state by enhancing the greenhouse effect of water vapor. This is often simply called the “water vapor feedback.”. We quantify the interannual variations (IAVs) of tropospheric O 3 concentrations in China. The roles of variations in meteorological parameters and anthropogenic emissions are examined. Surface-layer O 3 concentrations over NC, SC, and SCB have IAVs of e%, e%, and e%, respectively. parison and to assess the simulation of upper tropospheric temperature. A HIRS water vapor channel is used to analyze the CCM3-simulated emission of outgoing radi-ance from water vapor in the upper troposphere.
