EL MODELO MPAS-A (MODEL FOR PREDICTION ACCROSS SCALES-ATMOSPHERE) HA SIDO RECIENTEMENTE DESARROLLADO POR NCAR Y LANL (USA) PARA PRODUCIR UN MODELO GLOBAL DE USO ABIERTO PARA LA COMUNIDAD CIENTIFICA. MPAS-A NO SUFRE DE INCONVENIENTES QUE TENIA EL MODELO REGIONAL WRF EN SU CONFIGURACION GLOBAL. INCORPORA NOVEDADES TALES COMO EL USO DE UNA MALLA VORONOI NO ESTRUCTURADA, UNA COORDENADA VERTICAL HIBRIDA, LA CAPACIDAD DE TRABAJAR EN RESOLUCION VARIABLE Y LA POSIBILIDAD DE EMPLEAR DATA ASSIMILATION RESEARCH TESTBED (DART) COMO SISTEMA DE ASIMILACION. MEDIANTE ESTOS DOS COMPONENTES (MPAS-A Y DART) SE DESARROLLARA UN SISTEMA DE ASIMILACION GLOBAL DE RESOLUCION AUMENTADA EN TORNO A LA PENINSULA IBERICA. LA MALLA SERA ESPECIFICA, CENTRADA EN LA PENINSULA IBERICA, Y SU ESTRUCTURA ESTARA OPTIMIZADA PARA EL CALCULO CON ALTA RESOLUCION SOBRE LA PENINSULA IBERICA, MIENTRAS QUE LAS SIMULACIONES SERAN GLOBALES._x000D_ _x000D_ EL PRIMER OBJETIVO SE BASA EN DESARROLLAR UN SISTEMA GLOBAL DE ASIMILACION DE DATOS ATMOSFERICOS CON RESOLUCION AUMENTADA ALREDEDOR DE LA PENINSULA IBERICA. EL SEGUNDO OBJETIVO DEL PROYECTO CONSISTE EN EXPLORAR LA VIABILIDAD DE EMPLEAR ESTE MODELO EN CONFIGURACION DE RESOLUCION VARIABLE COMO HERRAMIENTA DE DOWNSCALING NUMERICO. SE VERIFICARA EN DETALLE EL FUNCIONAMIENTO DEL MODELO EN PROBLEMAS DE INTERES PARA EL GRUPO TALES COMO LOS BALANCES DE HUMEDAD O EL VIENTO SUPERFICIAL. FINALMENTE, EL TERCER OBJETIVO DEL PROYECTO SE CENTRARA EN DESARROLLAR PRACTICAS NUMERICAS PUBLICAS SOBRE LA ESTRUCTURA DE LA CIRCULACION GENERAL ATMOSFERICA UTILIZANDO PARA ELLO EL MODELO MPAS-A._x000D_ _x000D_ PARA ALCANZAR EL PRIMER OBJETIVO SE REALIZARA UNA INTEGRACION PLURIANUAL DEL MODELO MPAS-A CON MALLA DE RESOLUCION AUMENTADA SOBRE LA PENINSULA IBERICA (DA_HIRES), CONDICIONES INICIALES Y DE CONTORNO DE UN REANALISIS (ERA INTERIM) O DATOS OPERATIVOS TALES COMO GFS DURANTE EL PERIODO (ORIENTATIVAMENTE) 2010-2014 UTILIZANDO ASIMILACION DE DATOS EMPLEANDO DART (ENKF). _x000D_ _x000D_ PARA CUMPLIR EL OBJETIVO DOS SE REALIZARA UNA INTEGRACION SIN ASIMILACION DE DATOS DE LA CONFIGURACION CON MALLA VARIABLE EN EL MISMO PERIODO (EXPERIMENTO NODA_HIRES). UN TERCER EXPERIMENTO (NODA_LOWRES) SE REALIZARA CON UNA RESOLUCION GLOBAL CONSTANTE SIMILAR A LA DE LA ZONA DE BAJA RESOLUCION (OCEANO PACIFICO) EN EL EXPERIMENTO DA_HIRES SIN DA. LA COMPARACION DE NODA_HIRES Y NODA_LOWRES CUANTIFICARA LAS POSIBILIDADES DE MPAS-A COMO HERRAMIENTA DE DOWNSCALING NUMERICO. LOS RESULTADOS DE NODA_HIRES Y DA_HIRES SE COMPARARAN CON LOS RESULTADOS DE LAS INTEGRACIONES REALIZADAS POR EL GRUPO SOBRE LA PENINSULA IBERICA EMPLEANDO WRF Y WRFDA EN EL PROYECTO CGL2013-45198-C2-1-R. EN TODOS LOS CASOS LA VERIFICACION SE CENTRARA EN VARIABLES DE SUPERFICIE TALES COMO PRECIPITACION, TEMPERATURA, VIENTO Y TAMBIEN EN EL ANALISIS DEL CICLO HIDROLOGICO SOBRE LA PENINSULA IBERICA. _x000D_ _x000D_ FINALMENTE, PARA CUMPLIR EL TERCER OBJETIVO, SE PREPARARAN DIVERSOS MATERIALES DE USO LIBRE QUE PERMITIRAN CONFIGURAR DE FORMA SENCILLA EXPERIMENTOS NUMERICOS EN TORNO AL USO DE MPAS COMO LABORATORIO DE EXPLORACION DE LA CIRCULACION GENERAL ATMOSFERICA. ESTOS EXPERIMENTOS ESTARAN DESTINADOS A LA ENSEÑANZA EN NIVELES DE MASTER._x000D_ _x000D_ EL SALTO A UNA ESCALA GLOBAL MANTENIENDO LA OPCION DE TRABAJAR CON ASIMILACION DE DATOS Y RESOLUCION AUMENTADA SOBRE LA PENINSULA IBERICA ABRIRA AL GRUPO PROPONENTE POSIBILIDADES INTERESANTES PARA ENFRENTARSE A NUEVOS PROBLEMAS QUE HASTA AHORA NO ERAN ACCESIBLES POR EL USO DE UN MODELO REGIONAL DE AREA LIMITADA.

THE MODEL MPAS-A (MODEL FOR PREDICTION ACCROSS SCALES-ATMOSPHERE) HAS RECENTLY BEEN DEVELOPED BY NCAR AND LANL (USE) TO PRODUCE A GLOBAL OPEN-USE MODEL FOR THE SCIENTIFIC COMMUNITY. MPAS-A DOES NOT SUFFER FROM THE INCONVENIENCE OF THE WRF REGIONAL MODEL IN ITS GLOBAL CONFIGURATION. IT INCORPORATES NOVELTIES SUCH AS THE USE OF AN UNSTRUCTURED VORONOI MESH, A HYBRID VERTICAL COORDINATE, THE ABILITY TO WORK IN VARIABLE RESOLUTION AND THE POSSIBILITY OF USING DATA ASSIMILATION RESEARCH TESTBED (DART) AS AN ASSIMILATION SYSTEM. THROUGH THESE TWO COMPONENTS (MPAS-A AND DART) A SYSTEM OF GLOBAL ASSIMILATION OF INCREASED RESOLUTION AROUND THE IBERIAN PENINSULA WILL BE DEVELOPED. The MALLA SERA SPECIFIC, CENTRATED IN THE IBERICAL PENINSULA, AND YOUR STRUCTURE IS OPTIMITED FOR THE QALCLE WITH HIGH RESOLUTION ON THE IBERICAL PENINSULA, MIENTRAS THAT THE SIMULATIONS BE GLOBAL._x000D_ _x000D_ THE FIRST OBJECTIVE IS IN DEVELOPMENT a GLOBAL SYSTEM of assimilation of ATMOSFERIC DATA WITH INCLUDED RESOLUTION OF THE IBERICA PENINSULA. THE SECOND OBJECTIVE OF THE PROJECT IS TO EXPLORE THE FEASIBILITY OF USING THIS MODEL IN VARIABLE RESOLUTION CONFIGURATION AS A TOOL OF NUMERIC DOWNSCALING. THE OPERATION OF THE MODEL SHALL BE CHECKED IN DETAIL IN PROBLEMS OF INTEREST TO THE GROUP SUCH AS MOISTURE BALANCES OR SURFACE WIND. Finally, THE THIRD OBJECTIVE OF THE PROJECT will focus on developing numerical PRACTICAL PUBLICS ON THE STRUCTURE OF THE ATMOSFER GENERAL CIRCULLATION USED FOR THE MODEL MPAS-A._x000D_ _x000D_ TO ARE THE FIRST OBJECTIVE WORKING PLURIANUAL INTEGRATION OF THE MPAS-A MODEL WITH UNITED RESOLUTION MALLATION ON THE IBERICAL PENINSULA (DA_HIRES), INICIAL CONDITIONS AND CONTENT OF A Reanalysis (ERA INTERIM) OR OPERATIVE DATA AS GFS DURING THE PERIOD (orientatively) 2010-2014 USING DATA EMPLEANDO DART (ENKF). _x000D_ _x000D_ to CUMPLY THE OBJECTIVE TWO A INTEGRATION WITHOUT THE DATA OF CONFIGURATION WITH VARIABLE MALLA IN THE MISM PERIOD (EXPERIMENT NODA_HIRES). A THIRD EXPERIMENT (NODA_LOWRES) WILL BE PERFORMED WITH A CONSTANT GLOBAL RESOLUTION SIMILAR TO THAT OF THE LOW RESOLUTION ZONE (OCEAN PACIFIC) IN THE DA_HIRES EXPERIMENT WITHOUT GIVING. THE COMPARISON OF NODA_HIRES AND NODA_LOWRES WILL QUANTIFY THE POSSIBILITIES OF MPAS-A AS A NUMERICAL DOWNSCALING TOOL. THE RESULTS OF NODA_HIRES AND DA_HIRES WILL BE COMPARED WITH THE RESULTS OF THE INTEGRATIONS MADE BY THE GROUP ON THE PENINSULA IBERICA USING WRF AND WRFDA IN PROJECT CGL2013-45198-C2-1-R. IN ALL CASES THE VERIFICATION WILL FOCUS ON SURFACE VARIABLES SUCH AS PRECIPITATION, TEMPERATURE, WIND AND ALSO ON THE ANALYSIS OF THE HYDROLOGICAL CYCLE ON THE IBERIAN PENINSULA. _x000D_ _x000D_ finally, TO CUMPLY THE THIRD OBJECTIVE, MATERIAL DEVELOPMENTS OF FREE USE will be prepared that will allow NUMERIC FORM FORM to be established in part to the use of MPAS as the Exploration of the General Atmosphere Cycle. These EXPERIMENTS will be DESTINED to teaching in MASTER LEVELS._x000D_ _x000D_ THE STAFF TO A GLOBAL ESCAL MASTERING THE OPTION OF WORKING WITH DATA Assimilation and Increased RESOLUTION ON IBERICA PENSULA will open up to the PROPONENT POSIBILITIES GROUP we are interested in embracing our new proposals that you are now not accustomed to by the use of a regional model of limitised AREA.
