China ABSTRACT In this paper, we use ASCAT and MODIS data to analyze wind field, the temperature and the chlorophyll concentration distribution in Bohai Sea and Yellow Sea mixed zone and compare characteristics with the first 10 years (Except the wind field, it is only 6 years with ASCAT data). We found that high wind weather is too few in winter of 2013, the northerly winds are dominant, and the sea surface temperatures are also high and low chlorophyll concentration into the mixing zone of Yellow Sea and the Bohai Sea trend. There is 6℃ to 8℃ sea water into the Bohai Sea. 1. INTRODUCTION The Bohai Sea is China’s inland Sea (37°07′N to 41°0′N and 117°35′E to 121°10′E, about 7.7 × 10 4 km 2 ) and it surrounds by the Liaodong and Shandong peninsulas. The average depth of the Bohai Sea is 18 meters and is dominated by mud and silt-mud sediments. The Bohai Sea consists of Laizhou Bay, Bohai Bay, Liaodong Bay, and the central basin. The sea is nearly enclosed by shallow waters and has a high, rich-quality fishery, a harbor, petroleum, landscapes, and sea salt resources [1]. However, the Bohai strait is the only channel connects the open seas- Yellow Sea. The Yellow sea is a semi-closed shelf shallow sea ， Yellow Sea downfold from the west to Jeju Island to the north to the depth of 70-100 m. In the East China Sea, the northeast, south of Jeju Island, there is a flow along the northwest into the south Yellow Sea; it is referred to the Yellow Sea warm current on oceanography. It was the only foreign water in Yellow Sea and has the characteristics of high temperature and high salt and low dissolved oxygen content [2]. Its’ strong and weak change on Yellow Sea and Bohai Sea water exchange, as well as the whole Bohai Sea environmental impact has been the concern of the people. So to study the connected to the Yellow Sea and Bohai Sea zone’s the temperature, the chlorophyll concentration distribution and the 4411 978-1-4799-5775-0/14/$31.00 ©2014 IEEE IGARSS 2014
