ON THE INFLUENCES OF LARGE-SCALE INHOMOGENEITY OF SEA TEMPERATURE UPON THE OCEANIC WAVES IN THE TROPICAL REGIONS-PART II: LINEAR NUMERICAL EXPERIMENTS

By using a linear oceanic mixed layer model, the long period waves in the tropical ocean are investigated numerically. Due to the inhomogeneity of the large-scale average sea temperature field of the ocean in tropical regions, besides the westward propagating equatorial Rossby wave to be modified, there will be a kind of long period thermal wave which propagates eastward under certain oceanic background conditions. Under the influences of these two kinds of waves, the propagating and evolving processes of the sea surface temperature anomalies (SSTA) are clearly shown by numerical experiments. The results of numerical experiments are consistent with the ones obtained by the theoretical analysis in Part I. The possible relationship between these two kinds of waves and El Nino events is also discussed indirectly.  相似文献   

TELECONNECTIONS OF THE SEA SURFACE TEMPERATURE IN THE INDIAN OCEAN WITH SEA SURFACE TEMPERATURE IN THE EASTERN EQUATORIAL PACIFIC, AND WITH THE 500 hPa GEOPOTENTIAL HEIGHT FIELD IN THE NORTHERN HEMISPHERE     

季振刚  巢纪平 《大气科学进展》1987,(3)

The observational data of global sea surface temperature and the 500 hPa geopotential height field in the Northern Hemisphere are used to get two teleconnection patterns. The time interval of the data is from January 1950 to December 1979. The results show that the sea surface temperature anomalies in the Indian Ocean have evident positive correlation with the SSTA in the eastern Pacific and obvious teleconnection with the 500 hPa geopotential height field in [he Northern Hemisphere.  相似文献
