摘要
在本研究题目的第—部分中,作者由热量方程利用高空温压场和表面风的平均资料,计算了北半球1月和7月对流层下半部热源和热汇的分布,并讨论了它们的地理分布的特点。作者利用辐射、凝结和湍流等加热过程来解释热源和热汇的分布情况。并将热源和热汇的水平分布图和沿纬圈方向的平均值,与过去其他人的工作在源汇强度和分布形势上予以详细比较。
In 1st part of this paper,we have calculated the distribution of the mean heat sources and sinks in lower troposphere.The Local change of the mean temperature,or the 1000—500mb thickness h,is■(1) Assuming a steady state,and taking mean over the range of integration,we obtain.■(2) where Q is the heat gained or lossed byùnit mass of air in unit time.ω=dp/dt is the vertical velocity,■,as a constant,p_(0)=1000 mb,■=500 mb,m represents the mean over 1000—500 mb.Using the mean charts of 1000—500 mb thickness and 700 mb topography,we can calculatethe 1st term of(2)by geostrophic approximation.(Fig.5—6)
