                         the driver of tropical sea level pressure changes,'' Bayr and 
                         Dommenget proposed a simple model of temperature-driven air 
                         redistribution to quantify the ratio between changes of sea level 
                         pressure p(s) and mean tropospheric temperature T-a in the 
                         tropics. This model assumes that the height of the tropical 
                         troposphere is isobaric. Here problems with this model are 
                         identified. A revised relationship between ps and Ta is derived 
                         governed by two parameters-the isobaric and isothermal 
                         heights-rather than just one. Further insight is provided by the 
                         earlier model of Lindzen and Nigam, which was the first to use the 
                         concept of isobaric height to relate tropical ps to air 
                         temperature, and they did this by assuming that isobaric height is 
                         always around 3 km and isothermal height is likewise near 
                         constant. Observational data, presented here, show that neither of 
                         these heights is spatially universal nor does their mean values 
                         match previous assumptions. Analyses show that the ratio of the 
                         long-term changes in ps and T-a associated with land-sea 
                         temperature contrasts in a warming climate-the focus of Bayr and 
                         Dommenget's work-is in fact determined by the corresponding ratio 
                         of spatial differences in the annual mean p(s) and T-a. The latter 
                         ratio, reflecting lower pressure at higher temperature, is 
                         significantly impacted by the meridional pressure and temperature 
                         differences. Considerations of isobaric heights are shown to be 
                         unable to predict either spatial or temporal variation in p(s). As 
                         noted by Bayr and Dommenget, the role of moisture dynamics in 
                         generating sea level pressure variation remains in need of further 
                         theoretical investigations.",
