Title:Three-dimensional structure of tropical non migrating tides and their response to MJO resolved from the radio occultation data [poster]
Abstract: By analyzing multiyear RO observations, the tropical nonmigrating tides in the free troposphere and lower stratosphere are investigated. Nonmigrating tides clearly demonstrate internal gravity wave characteristics, excited from two major continents, Africa and South America; and propagating westward and eastward from the source. Those dominant wavenumbers, such as DE3 and DW5, D0 and DW2, show clear seasonal variability and different propagating modes. Further investigation by compositing RO data based on MJO phases, indicates the MJO convection can influence the diurnal temperature amplitude modestly, constrained over the land, with nonsynchronous phases with MJOs.
