A manutencao da circulacao atmosferica no verao sobre a America do Sul e estudada do ponto de vista dos balancos de vorticidade e de energia cinetica. Considerou-se 5 anos de dados analisados diarios (1 nov. 1985 - 31 jan. 1991), globais, obtidos do NMC, as 12 UTC. O balanco de vorticidade incluindo os transientes nao foi muito definido. O balanco de energia cinetica mostrou que o ciclo de energia sobre a America do Sul, no verao, se da da seguinte forma: EPD para Kx, atraves do termo.... e, de Kx para K..., principalmente atraves do termo de interacao...O estudo de periodicidades nos parametros de energia cinetica mostrou varios tipos de oscilacoes: o ciclo anual, de 30-60 dias e oscilacoes de curto periodo, sugerindo a presena de transientes. na America do Sul, as interacoes entre as escalas sazonal e intrasazonal foram mais dominantes. A energia cinetica local mostrou o papel dos transientes na regiao do cavado sobre o Atlantico Sul e das interacoes sazonais e intrasazonais na regiao da Alta da Bolivia. Maiores interacoes ocorreram proximo ou na regiao das Zona de convegencia do Atlantico Sul (ZCAS). |

Many remote sensing-based evapotranspiration (RSBET) algorithms have been proposed in the past decades and evaluated using flux tower data, mainly over North America and Europe. Model evaluation across South America has been done locally or using only a single algorithm at a time. Here, we provide the first evaluation of multiple RSBET models, at a daily scale, across a wide variety of biomes, climate zones, and land uses in South America. We used meteorological data from 25 flux towers to force four RSBET models: Priestley?Taylor Jet Propulsion Laboratory (PT-JPL), Global Land Evaporation Amsterdam Model (GLEAM), Penman?Monteith Mu model (PM-MOD), and Penman?Monteith Nagler model (PM-VI). E ET was predicted satisfactorily by all four models, with correlations consistently higher (?20.6ER) for GLEAM and PT-JPL, and PM-MOD and PM-VI presenting overall better responses in terms of percent bias (?? ?1010EPBIAS%). As for PM-VI, this outcome is expected, given that the model requires calibration with local data. Model skill seems to be unrelated to land-use but instead presented some dependency on biome and climate, with the models producing the best results for wet to moderately wet environments. Our findings show the suitability of individual models for a number of combinations of land cover types, biomes, and climates. At the same time, no model outperformed the others for all conditions, which emphasizes the need for adapting individual algorithms to take into account intrinsic characteristics of climates and ecosystems in South America.
