DIURNAL VARIATIONS IN OCEAN-ATMOSPHERE ENERGY EXCHANGE AND CHEMICAL FACTORS OF SEA-SURFACE OF ZENGMU SHOALS WATERS IN EARLY JUNE, 1985

1985年6月初曾母暗沙水文气象印海面化学要素同步连续观测资料的分析结果表明,该海区海一气能量交换和海面化学要素含量的周日变化有如下特点:1).本海区海一气能量交换主要是田海洋传给大气;2)大气不稳定时,能显交換量增大,ΣCO_2含量减小,而大气稳定时则与此相反;3)活性硅酸盐含量的周日变化与能量交换量周日变化趋势一致;4)能量交换量的周日变化与NH_4-N含量的周日变化相似,与NO_3-N含量的周日变化趋势基本相反,该海区海一气能量交换不仅与水文气象条件和浮游植物活动有关,而且与海面化学要素含量有密切关系。

This paper reports the analyses of synchronous consecutive observation data of hydrometeorology and sea-surface chemical factors of Zengmu Shoals Waters in early June, 1985. The results show that the diurnal variations in ocean-atmosphere energy exchange and the content of sea-surface chemical factors in this area as follow, 1) In this region area, energy is mainly passed from water to atmosphere; 2) When atmosphere's condition is unstable, the energy-exchange will increase while the content of CO2 decrease, and when atmosphere is stable, they will go to the contrary; 3) The diurnal-variation in ocean-atmosphere energy exchange tends to be consistent with that in the content of active silicate and similar with that in the content of NH4-N, but opposite to that in the content of NO3-N. The ocean-atmosphere energy exchange of the area is not only under the influence of the condition of hydrometeorology and the activity of phytoplankon, but also the content of sea-surface chemical factors as well.
