KeywordFive-day Planetary Wave Polar Mesosphere Cloud Ice Water Content
AbstractThe temperature and column ice water content (IWC) of polar mesospheric clouds (PMCs) have been simultaneously measured by the Solar Occultation for Ice Experiment (SOFIE) on board NASA's Aeronomy of Ice in the Mesosphere satellite since April 2007. The 8year (2007-2014) data of the temperature and IWC are used to extract the 5day planetary waves (PWs) with zonal wave numbers ranging from -1 to -3 (eastward propagating mode, E1-E3), 0 (stationary mode, W0), and 1 to 3 (westward propagating mode, W1-W3) in the polar stratosphere and mesosphere. The 5day PWs in temperature are stronger in the polar winter stratosphere and mesosphere and exhibit substantial interhemispheric asymmetry. The date-height distributions of the 5day waves coincide with those of the eastward jet in each hemisphere. This indicates that the 5day PWs might be generated from barotropic/baroclinic instability in the polar stratosphere. The relative strengths of 5day PWs decrease with increasing wave numbers. The E1 (W1) 5day PW is stronger than any other mode in the winter stratosphere and lower mesosphere (summer upper mesosphere). SOFIE temperature and IWC data are derived from simultaneous measurements in the same air column and thus provide a good opportunity to study the phase relationship between the 5day PWs in temperature and IWC. Our analyses show that the phase shifts of W1 5day PW in temperature relative to that in IWC have a mean of -2.0h (0.3h) with a standard deviation of 3.8h (4.2h) in the northern (southern) polar region. This indicates that the formation of the W1 5day PW in PMCs is controlled mainly by the W1 5day PW in temperature and influenced by other factors and is consistent with previous studies.
