A one - dimensional oceanic mixed layer model with the m - y level - 2. 5 turbulence closure schemes is employed. the rate of energy loss by breaking waves is estimated by parameterization and incorporated into the model as a source of turbulence kinetic energy ( tke ) by modifying the existing surface boundary condition of tke equation. the velocity field and turbulence energy budget are calculated under different forcing conditions ( the results given below are for a wind speed of 20 m / s. )
採用一維2 . 5階湍封閉混合層模式，根據參數化方法對波浪破碎導致的能量耗散率進行了估計，通過改變湍動能方程的上邊界條件引入波浪破碎對湍動能生成的影響，計算了不同風應力強迫下的混合層流場結構和湍能量收支（下述給出的結果是取風速為20m s得到的） 。 -
( 5 ) the frequency modulation effects of positive ( negative ) dipole and positive ( negative ) unipole forcing source on lfo have the same sensitive region
（ 5 ）正（負）偶極和正（負）單極對大氣的低頻振蕩調制有相同的敏感區。 -
( 2 ) the stronger ( weaker ) the intensity of dipole or unipole forcing source and basic flow, the periods of lfo the shorter ( longer )
（ 2 ）偶、單極強迫熱源強度和基流強度的增強（減弱） ，使得大氣低頻振蕩周期有縮短（延長）的趨勢。 -
Then numerical experiments on forcing dissipation and heating response of dipole ( unipole ) are carried out using global spectral model of quasi - geostrophic barotropic vorticity equation. for every experiment model integration is run for 90 days on the condition of three waves quasi - resonance. the results are given as follows : ( 1 ) under the effects of basic flow intensity and dipole ( unipole ) forcing source, there exist strong interaction among the three planetary waves, and there also exist quasi - two - week and intra - seasonal oscillation of the three planetary waves
然後，用數值試驗的方法，應用強迫耗散準地轉正壓渦度方程的全球譜模式，並在方程中考慮了偶（單）極子的熱力強迫作用，在三個行星波準共振的條件下，模式共積分90d ，得出： （ 1 ）在基本氣流強度和偶（單）極強迫熱源的共同作用下，三個行星波之間存在很強的波?波相互作用，且波動振蕩呈現準雙周和季節內振蕩。 -
( 3 ) the frequency modulation effects of positive ( negative ) dipole or unipole forcing source on lfo in the mid - high latitudes are difference
（ 3 ）正、負偶（單）極強迫源對中高緯大氣的低頻振蕩調製作用不同。 -
( 4 ) the frequency modulation effects of positive dipole ( unipole ) forcing source on lfo is stronger than negative dipole ( unipole ), and the wave oscillation quicken evidently
（ 4 ）正偶（單）極強迫源對大氣低頻振蕩的調製作用強于負偶（單）極，波動振蕩明顯加快。 -
It was demonstrated that in june and december, as far as the daily averaged rates were concerned, whether the aerosol concentration is the heat source or the cold one depends on the aerosol density. however, the relation bears nonlinear features. in the diurnal range, the effects of the aerosol radiative forcing on the atmospheric stability depend on the vertical distribution and density of the aerosol
結果表明，從氣候角度而言，氣溶膠濃度的差別使得即使是在6月份，氣溶膠層既可以是冷源也可以是熱源從天氣尺度而言，氣溶膠的垂直分佈和濃度對層結穩定度有著重要影響，並由此從物理上指出了沙塵暴天氣過程中輻射效應所起的重要作用。
