卫星高度表数据的分析建议长 Rossby 波浪在副热带的太平洋放大了的 intraseasonal 的宣传速度比免费 Rossby 波浪由班机理论和在太平洋的东方边界反映的长 Rossby 波浪基本上同意的 intraseasonal 的宣传速度预言了的第一模式的 baroclinic 的快第一模式的 baroclinic 与班机理论加速免费 Rossby 波浪。如果我们不区分二种长 Rossby 波浪并且在整个盆估计 Rossby 波浪速度,阶段速度仅仅长比线性理论高是 25% Rossby 波浪速度。长 Rossby 波浪在副热带的太平洋放大了的 intraseasonal 的宣传速度的 Theacceleration 由于存在向西 thermolcline 平均数流动。
The analysis of the satellite altimeter data suggests that the propagating speed of intraseasonal long Rossby wave amplified in the subtropical Pacific Ocean is faster than that of first mode baroclinic free Rossby wave predicted by the liner theory and the propagating speed of intrascasonal long Rossby wave reflected in the eastern boundary of Pacific Ocean agrees basically with the liner theory speed of first mode baroelinic free P, ossby wave. If we do not distinguish the two kinds of hmg Rossby waves and estimate the Rossby wave speed in the whole basin, the phase speed is merely 25% higher than the linear theory long Rossby wave speed. The acceleration of the propagating speed of intraseasonal long Rossby wave amplified in the subtropical Pacific Ocean is due to the existence of westward thermolcline mean flow.
