| One possible explanation for tropical sea surface temperature (SST) interannual variability is that it can be accurately described by a linear auto-regressive model with damped coupled feedbacks and stochastic forcing. This auto-regressive model can be viewed is a “null hypothesis” for tropical SST variability. This paper advances a new coupled general circulation model (CGCM) coupling strategy, called an interactive ensemble as a method to test this null hypothesis. The design of the interactive ensemble procedure is to reduce the stochastic variability in the air-sea fluxes applied to the ocean component while retaining the deterministic component of the coupled feedbacks. The interactive ensemble procedure uses multiple realizations of the atmospheric... |

| In this study we show a teleconnection pattern relating Outgoing Longwave Radiation (OLR) anomalies over the western Pacific Ocean and sea surface temperature anomalies (SSTA) over the western Indian Ocean over two seasons (Sept-Oct-Nov and Dec-Jan-Feb) at zero lag from observations and atmospheric general circulation model (AGCM) integrations. This teleconnection pattern suggests that a positive SSTA in Sept-Oct-Nov (SON) and Dec-Jan-Feb (DJF) seasons over the western Indian Ocean increases the contemporaneous positive OLR anomalies over the western Pacific Ocean. This teleconnection pattern is also simulated by the Center for Ocean-Land- Atmosphere studies (COLA) AGCM forced with observed SST’s. From the experimental COLA AGCM runs (wherein the Pacific... |

| El golfo de Ana María constituye una zona con grandes reservas naturales y de condiciones climáticas muy específicas, que la ubica como favorable para explotar por dos sectores económicos de importancia nacional: la pesca y el turismo; el que cobra mayor auge en los últimos años. Se realizó una evaluación de las condiciones hidrometeorológicas en su porción central, determinándose en diecisiete puntos de muestreo durante octubre de 2011, el comportamiento de cinco elementos meteorológicos: nubosidad, dirección y velocidad del viento, temperatura y fenómenos atmosféricos. Todas las mediciones y observaciones fueron realizadas por medio de una metodología elaborada previamente, aplicable a zonas alejadas del alcance máximo de las estaciones de... |

| A cluster algorithm is applied to the zonal mean zonal wind and 500 hPa height from winter monthly means (for the period 1948-2002), obtained from the reanalyses of the National Centers for Environmental Prediction - National Center for Atmospheric Research (NCEP/NCAR). Four reproducible and robust clusters are found: two regimes represent the opposite phases the Northern Hemisphere Annular mode (NAM), and two regimes represent the opposite phases of a pattern which can be identified with the Cold Ocean-Warm Land (COWL) pattern. This identification is accomplished by regressing the zonal mean zonal wind on the COWL-index derived from 500 hPa height data by Wu and Straus [2003]. |
