The images of the sea surface roughness observed by PALSAR on ALOS over the Philippine Archipelagos were studied with other opportunities of satellite observations including MODIS and other measurement to understand an imaging mechanism by SAR. The Tabulas Strait and the Mindanao Sea, which are connecting the Pacific and the South China Sea and blocking the North Equatorial Current, were select...

Sea clutter refers to the backscattered returns from a patch of the sea surface illuminated by a transmitted radar pulse. Since the complicated sea clutter signals depend on the complex wave motions on the sea surface, it is reasonable to study sea clutter from nonlinear dynamics, especially chaos, point of view, instead of simply based on random processes. In the past decade, Dr. Simon Haykin’...

Introduction The first in-situ field observations of Antarctic austral summer sea-ice melt were made in the Bellingshausen Sea by Arctowski (1908) on Belgica in 1899, and later by Wordie (1921) during the ill-fated drift of Endurance in the Weddell Sea from 1914-1916. It has been 100 years since these pioneering ship drift experiments, yet little more is known about the spatial extent, duration...

Indian Ocean is known as a source of moisture for southeast of Iran due to summer precipitation. In this study, in order to investigate the role of SST of Indian Ocean, and the convergence and divergence fields in the precipitation of southeast of Iran, precipitation data of five synoptic stations were used during 2000-2010, including Iranshahr, Khash, ChahBahar, Zabul, and Saravan. To investig...

Definition Wind is air in motion and is basically a vector quantity with a magnitude (speed) and a direction. Ocean surface stress is another vector quantity closely related to wind; it is the turbulent transfer of momentum between the ocean and the atmosphere. Their different applications are summarized in the section "Scientific Significance".

A method of investigation sea surface roughness by analysis polarization images is suggested. Equipment and software were developed and tested at the Pacific Oceanological Institute (POI) in 2003 2004. Equipment includes a polarization camera and systems of floats. The float heights obtained from its image coordinates. The slopes of the sea surface were determined as orientation triangles, form...

There is a clear positive correlation between boreal summer tropical Atlantic sea-surface temperature and annual hurricane numbers. This motivates the idea of trying to predict the sea-surface temperature in order to be able to predict future hurricane activity. In previous work we have used simple statistical methods to make 5 year predictions of tropical Atlantic sea surface temperatures for ...
