Sentences with phrase «scale wind anomalies»

Rising air over the Atlantic subsides over the equatorial Pacific, causing central Pacific sea surface cooling, which in turn reinforces the large - scale wind anomalies.

Not exact matches

Variability with MJO characteristics (e.g., convection and wind anomalies of the correct spatial scale that propagate coherently eastward with realistic phase speeds) is simulated in many contemporary models (e.g., Sperber et al., 2005; Zhang, 2005), but this variability is typically not simulated to occur often enough or with sufficient strength so that the MJO stands out realistically above the broadband background variability (Lin et al., 2006).

The basin - scale winds over the Pacific / NA region (PCI) represent anomaly intervals of general flow direction and intensity (related to ALPI, NPO, and indirectly to PDO).

southern oscillation a large - scale atmospheric and hydrospheric fluctuation centered in the equatorial Pacific Ocean; exhibits a nearly annual pressure anomaly, alternatively high over the Indian Ocean and high over the South Pacific; its period is slightly variable, averaging 2.33 years; the variation in pressure is accompanied by variations in wind strengths, ocean currents, sea - surface temperatures, and precipitation in the surrounding areas

Environmental variables estimated over larger spatial and temporal scales included the upwelling index (UI) for 48 ° N, 125 ° W (http://www.pfeg.noaa.gov), an indicator of upwelling strength based on wind stress measurements, as well as the Pacific Decadal Oscillation (PDO, http://jisao.washington.edu/pdo/PDO.latest), a composite indicator of ocean temperature anomalies [33], seawater temperature from Buoy 46041 ∼ 50 km to the southwest from Tatoosh (www.ndbc.noaa.gov), and remote sensing of chl a (SeaWiFS, AquaModis).
