Large scale, stationary, frontal features in the Benguela Current system     

D. van Foreest  F.A. Shillington  R. Legeckis 《Continental Shelf Research》1984,3(4):465-474

Large scale, stationary features of the Benguela Current system have been observed on satellite infrared images. This paper attempts to establish the most likely dynamical framework required to explain the features. Although the observed features are clearly baroclinic, the wavelength of the 2.2 day period barotropic shelf wave (Buchwald and Adams, 1968, Proceedings of the Royal Society of London, A305, 235–250) fits the observed longshore spatial structure of the features well. The barotropic shelf wave model fails to explain the baroclinic nature and the stationary aspect of the observed features. More observational and theoretical work is necessary to understand the dynamics of these features.  相似文献   

Satellite monitoring of sea surface temperatures off China     

Legeckis  Richard  Campbell  Joan 《中国海洋湖沼学报》1988,6(3):243-250

Satellite measurements of global sea surface temperatures (SST) have been made since 1982 using the multi-channel radiometers (AVHRR) on NOAA polar orbiting satellites. A four year data set was accumulated at daily intervals and a spatial resolution of about 100 kilometers on an interactive computer system. The time lapse evaluation of the data revealed variations of the SST which were related to coastal and equatorial upwelling events as well as to the pronounced equatorial warming associated with the 1982–1983 El Niño. In the present study, satellite time series are used to describe the annual variability of the SST at selected locations along the coast of China, the Yellow Sea, the Sea of Japan and the Equatorial Indian and Pacific Oceans. Further study of the SST off China using higher resolution satellite data are also described.

Branching of the Tsushima Current in 1981–83     

Kuh Kim  Richard Legeckis 《Progress in Oceanography》1986,17(3-4)

Satellite-derived sea surface temperatures illustrate the variability of the path of the Tsushima Current in the Sea of Japan. In the spring of 1981 the Tsushima Current did not split as it left the Korea Strait and flowed into the Sea of Japan, which is contrary to the historical concept of branching. Warm water remained along Honshu, the main island of Japan, making a strong front oriented in an east-west direction. Hydrographic data confirm that this spring condition lasted through to the fall of 1981. On the other hand, during the springs of 1982 and 1983 the branching is evident from satellite images: one branch flowed northward along the east coast of Korea, and the other flowed eastward along Honshu of Japan.  相似文献
