WebAccording to the World Meteorological Organisation, the "first tropopause" is conventionally defined as the lowest level at which the lapse rate decreases to 2°C/km or less, … 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.
