论文摘要
本说明的目的是描述会议演讲中显示的几种气象特性（Marquet，2022年1月）针对湿空气的熵，Marquet（2011）中定义的相关潜在温度（$θ_s$）以及相关的潜在潜在涡度$ pv（θ_s）在Marquet（2014年）中定义了$ PV（$ PV），该地区$ pv（2014年）$ pv（表示对称不稳定性区域。
The aim of this note is to describe several meteorological properties shown in a conference talk (Marquet, January 2022) for the moist-air specific entropy, the associated potential temperature ($θ_s$) defined in Marquet (2011) and the associated potential vorticity $PV(θ_s)$ defined in Marquet (2014), with in particular regions of negative values of $PV(θ_s)$ close to the cold fronts that seems to indicate regions of symmetric instability.
