Projected Changes In Atmospheric Ridges Over The Pacific-North American Region Using Cmip6 Models, Paul C. Loikith, Deepti Singh, Graham P. Taylor
Projected Changes In Atmospheric Ridges Over The Pacific-North American Region Using Cmip6 Models, Paul C. Loikith, Deepti Singh, Graham P. Taylor
Geography Faculty Publications and Presentations
Projected changes in atmospheric ridges and associated temperature and precipitation anomalies are assessed for the end of the twenty-first century in a suite of 27 models contributing to phase 6 of the Coupled Model Intercomparison Project (CMIP6) under a high-end emissions scenario over the Pacific–North American region. Ridges are defined as spatially coherent regions of positive zonal anomalies in 500-hPa geopotential height. The frequency of ridge days in the historical period varies by geography and season; however, ridge days are broadly more common over the region in winter and least common in summer. The CMIP6 models are credible in reproducing …
Climate Model Evaluation Of Atmospheric Rivers Over The Contiguous United States, Ilan González-Hirshfeld
Climate Model Evaluation Of Atmospheric Rivers Over The Contiguous United States, Ilan González-Hirshfeld
Dissertations and Theses
Atmospheric rivers (ARs)--long corridors of intense atmospheric water vapor transport--significantly influence the hydrologic cycle and regional hydrometeorological extremes across the contiguous United States (CONUS). Ongoing and future climate change may alter AR characteristics and impacts, making confident climate model projections of future change, especially at regional scales, of critical importance. In order to better constrain uncertainty in such projections of future change, we perform a comprehensive climate model evaluation of AR climatology over the CONUS. Using an established AR detection algorithm, we evaluate the representation of ARs in historical simulations (1984-2013) from a suite of models participating in the sixth …
A 30-Year Climatology Of Meteorological Conditions Associated With Lightning Days In The Western United States, Dmitri Alexander Kalashnikov
A 30-Year Climatology Of Meteorological Conditions Associated With Lightning Days In The Western United States, Dmitri Alexander Kalashnikov
Dissertations and Theses
A 30-year climatology of lightning and associated synoptic meteorological patterns are characterized across the Western United States (WUS), utilizing a comprehensive composite analysis. Results generally show a preferred synoptic meteorological setup with positive 500-hPa geopotential height anomalies to the northeast of the location experiencing a lightning day, and negative sea level pressure anomalies co-located and to the northwest. Variation in preferred anomaly patterns across the western US reflects the divide between those areas affected by the North American monsoon system and areas outside the monsoonal core. Locations in the western Great Basin and northern Rocky Mountains, which are outside the …
