Cyclones in the Mediterranean region: the present and the doubled CO2 climate scenarios

摘要: This study investigates the variations of cyclonic activity in Mediterranean region that would be produced by doubling CO2 atmospheric content. The analysis is based on SLP (sea-level pressure) fields two 30 yr long time slice experiments ECHAM-4 model at T106 resolution, carried out DMI, simulating present and doubled scenarios. similar 2 climate characterized with a slightly, but statistically significant, higher overall number cyclones. simulation more extreme weather events, difference between scenarios hardly significant. No variation regions formation cyclones was clearly identified. An, admittedly small, both simulated using limited area (LAM) 0.25° resolution. These simulations do not suggest an increased resolution should add new major findings to results this study, possibility change signal evident because coarse remains open for further investigations. However, does show large regime due doubling.
