How can the tropopause be defined
WebBethan et al. (1996) defined the ozone tropopause using such an abrupt change of ozone mixing ratio, which is closely related to the dynamical tropopause defined using a potential vorticity. Figure 1 suggests that the ozone tropopause can be clearly defined even when the thermal tropopause becomes ambiguous in the Antarc-tic winter. WebHá 2 dias · Abstract. The Asian tropopause aerosol layer (ATAL) is a distinct feature during the Asian summer monsoon season with an impact on the regional radiative balance of the Earth's atmosphere. However, the source regions and the detailed transport pathways of ATAL particles are still uncertain. In this study, we investigate transport pathways from …

WebIn most cases, the tropopause is determined from gridded data, which are generally either analyses, reanalyses, or model output. The vertical resolution of such data is frequently of the order of 50 hPa in the vicinity of the tropopause. This raises the question of how accurately the tropopause can be determined from such coarse resolution data. WebEarth's atmosphere has a series of layers, each with its own specific traits. Moving upward from ground level, these layers are called the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. The exosphere gradually fades away into the realm of interplanetary space. Layers of the atmosphere: troposphere, stratosphere, mesosphere ...

Webtypically identify the location of the tropopause but do not provide any information on the structure of the troposphere‐ to‐stratosphere transition layer.

Web8 de mar. de 2008 · [5] This paper concentrates on the layer above the tropopause in the tropopause-based averages over which N 2 decreases with height from its maximum at the tropopause to more typical stratospheric values. In particular, we propose a definition for the depth of this layer and show how it varies with latitude in the annual and seasonal …
