Recent studies have demonstrated that the correlation between interannual variations of large-scale average temperature and water vapor is stronger and less height dependent in one GCM than in an objective analysis of radiosonde observations. To address this discrepancy, a GCM with a different approach to cumulus parameterization is used to explore the model dependence of this result, the effec...

Using General Circulation Models (GCMs) for tropical cyclone studies is difficult due to the relatively small size of the storms, the intense convection and multitudes of large-scale small-scale interactions. These are mostly unresolved at typical GCM resolutions of about 50-100 km, and still challenged at high resolutions between 12-30 km. Nevertheless, high-resolution GCMs are becoming a tool...

The representation of cloud systems and cloud-radiation interaction is considered to be one of major uncertainties in general circulation models (GCMs). This arises because (1) complete observations of cloud systems are impossible and available measurements are very limited; (2) cloud-radiation interactions are scale-dependent (Dudek et al. 1996) while current GCMs cannot explicitly resolve the...

homalium letestui pellegr (flacourtiaceae) is used traditionally by the ibibios of southern nigeria to treat stomach ulcer, malaria and other inflammatory diseases and yorubas of western nigeria as an antidote. the hepatoprotective effect of the stem extract (200-600 mg/kg) was evaluated by the assay of liver function parameters, namely total and direct bilirubin, serum protein and albumin, tot...

Global climate models (GCMs) are important tools for addressing climate change questions at a global scale. Recent research has attempted to combine outputs from multiple GCMs to quantify uncertainty in regional climate change, which may ultimately inform regional stakeholders and policy-makers. Using a case study, we illustrate a potential path toward improvement in an existing Bayesian formul...
