Modelos Climáticos

Climate models are numerical representations of the climate system based on the physical, chemical, and biological properties of its components, their interactions, and feedback processes. This article explores various types of climate models, their resolutions, and their applications in climate research and impact studies.

  1. Modelos Climáticos

  2. Los modelos climáticos son una representación numérica del sistema climático basada en las propiedades físicas, químicas y biológicas de sus componentes, sus interacciones y procesos de realimentación.

  3. Modelos de circulación general (atmósfera)

  4. Modelos de circulación general (océano)

  5. Modelos de circulación general (superficie terrestre)

  6. Los modelosclimáticosdescriben el pasado Ensembles of 4 realizations (R. A. Anthes, UCAR, 2003)

  7. Y el futuro. Variación de la temperatura global con respecto a1961-1990, ECHAM 5 MPI-OM

  8. RCPs … de acuerdo a los escenarios de emisión

  9. La resolución ha variado con el tiempo

  10. Para nuestrosestudiosnecesitamosmayor resolución ECHAM T42 ~ 2.5° Dt ~ 15 min T106 ~ 1° REMO 0.5° ~ 50 km 1/6° ~ 18 km Dt ~ 1 min

  11. Malla de un modelo regional

  12. Modelos Regionales

  13. REMO (Regional Model) Atmospheric General CirculationClimateModel. developed in the Max Planckinstitute of Metereology Hidrostatic (non hydrostatic soon!) - maximal grid resolution (hydrostatic): 1/10 degree. This grid resolution enables the model to resolve the most important topographic features Sofisticatedvegetationscheme State of the art soil, hydrographic and glaciar models Widelyusedforclimatic and impactstudies in Europe Echam4 physics Rotatedcoordinates

  14. PROYECTO ESCENA

  15. TheRegionallyCoupledModel (ROM) • Components: • The REgional atmospheric MOdel REMO • Global ocean model MPIOM (increased resolution in the Tropical Atlantic). • - A global Hydrological Discharge model (HD). • The models are coupled via OASIS coupler. • 1-3-6 hours coupled time step. • Lateral atmospheric and upper oceanic boundary conditions outside the coupled domain from reanalysis or global models.
