RISHeavy Daily Precipitation Events in the CMIP6 Worst-Case Scenario: Projected Twenty-First-Century Changes
Publisher: American Meteorological Society
Abstract: Heavy precipitation is often the trigger for flooding and landslides, leading to significant societal and economic impacts, ranging from fatalities to damage to infrastructure to loss of crops and livestock. Therefore, it ...
Tropical Intraseasonal Oscillation Appearing in Operational Analyses and in a Family of General Circulation Models
Publisher: American Meteorological Society
Abstract: The statistics of tropical intraseasonal variability are studied using European Centre for Medium-Range Weather Forecasts analyses and several ECHAM General Circulation Model experiments made with different model versions ...
Mediterranean Tropical-Like Cyclones in Present and Future Climate
Publisher: American Meteorological Society
Abstract: he Mediterranean has been identified as one of the most responsive regions to climate change. It has been conjectured that one of the effects of a warmer climate could be to make the Mediterranean Sea prone to the formation ...
Heavy Precipitation Events in a Warmer Climate: Results from CMIP5 Models
Publisher: American Meteorological Society
Abstract: n this work, the authors investigate possible changes in the distribution of heavy precipitation events under a warmer climate, using the results of a set of 20 climate models taking part in phase 5 of Coupled Model ...
Bidimensional Diagnostics, Variability, and Trends of Northern Hemisphere Blocking
Publisher: American Meteorological Society
Abstract: n this paper, Northern Hemisphere winter blocking is analyzed through the introduction of a set of new bidimensional diagnostics based on geopotential height that provide information about the occurrence, the duration, the ...
Mechanisms for ENSO Phase Change in a Coupled GCM
Publisher: American Meteorological Society
Abstract: The mechanisms leading to El Niño onset and termination in the ECHAM4/OPA coupled GCM are assessed and compared to observations and existing ENSO paradigms. At the equator as well as off equator, the patterns and timing ...
Effects of Land Surface–Vegetation on the Boreal Summer Surface Climate of a GCM
Publisher: American Meteorological Society
Abstract: A land surface model (LSM) has been included in the ECMWF Hamburg version 4 (ECHAM4) atmospheric general circulation model (AGCM). The LSM is an early version of the Organizing Carbon and Hydrology in Dynamic Ecosystems ...
A Diagnostic Study of the Indian Ocean Dipole Mode in El Niño and Non–El Niño Years
Publisher: American Meteorological Society
Abstract: The Indian Ocean dipole mode (IODM) is examined by comparing the characteristics of oceanic and atmospheric circulations, heat budgets, and possible mechanisms of IODM between El Niño and non?El Niño years. Forty-year ECMWF ...
Tropical Cyclone Count Forecasting Using a Dynamical Seasonal Prediction System: Sensitivity to Improved Ocean Initialization
Publisher: American Meteorological Society
Abstract: his study investigates the predictability of tropical cyclone (TC) seasonal count anomalies using the Centro Euro-Mediterraneo per i Cambiamenti Climatici?Istituto Nazionale di Geofisica e Vulcanologia (CMCC-INGV) Seasonal ...
Tropical Cyclone Interaction with the Ocean: The Role of High-Frequency (Subdaily) Coupled Processes
Publisher: American Meteorological Society
Abstract: AbstractThrough tropical cyclone (TC) activity the ocean and the atmosphere exchange a large amount of energy. In this work possible improvements introduced by a higher coupling frequency are tested between the two components ...
