概要 To discover water sources of agriculture irrigation for regions around Bohai Sea in China, sea ice in Bohai Sea is considered as the new kind of fresh water resource due to its lower salinity than sea...water, and the thermal characteristics of sea ice thickness affected by accumulative temperature were analyzed in the paper. The tentative results showed that the ice thickness growth is proportional to time in a second-degree polynomial under air temperature lower than -1.4℃. Before 39th hour, ice thickness increased very quickly, with a speed of 1.5mm/h, and after the 40th hour, its growth speed had decreased and maintained at approximately 0.24mm/h. The liner model was useful to study sea ice thickness and its evolution in the seasonal ice cover of Bohai Sea by an negative accumlated air temperature with ⊆-2℃ at 15cm height above ice surface with R[2]=0.9262 and 0.9044 in winter of 2003 and 2004.続きを見る
