![]() ![]() The recent generation of new reanalysis products were developed with many of these problems in mind and they offer a higher spatial resolution than previously possible. A further problem is the variation in data types assimilated by the atmospheric models, particularly during the transition to the satellite era in the 1980s, which can result in spurious variability in the reanalysis products and the blended datasets that make use of them ( Brodeau et al., 2010). The existence of such biases has led to the hybrid approach discussed later in which reanalysis fields are adjusted at the level of the surface meteorological variables prior to estimating the fluxes ( Large and Yeager, 2009 Brodeau et al., 2010). ![]() Specific examples include excessive estimates of the surface heat loss under conditions of high sea–air temperature difference ( Renfrew et al., 2002) and under-representation of stratiform cloud that can result in overestimates of the shortwave input to the ocean. However, both the NCEP and ERA40 reanalysis fields have been found to exhibit significant biases in the surface fluxes under certain conditions and, as a consequence, must be used with caution. ![]() The NCEP ( Kalnay et al., 1996) and European Centre for Medium range Weather Forecasting (ECMWF) ( Uppala et al., 2005) reanalysis products spanning periods of 40–50 years have been widely used by the community and their utility demonstrated in many areas, for example, the characterization of atmospheric modes of variability and their impacts ( Hurrell et al., 2003). The inclusion of atmospheric data and the constraints provided by the model physics potentially allows reanalyses to provide estimates of surface fluxes in regions sparsely sampled by ships that are more accurate than are possible from surface observations alone. Surface flux products from atmospheric reanalyses offer globally complete, high temporal resolution (6 hourly typically in some cases, 1 or 3 hourly) fields from numerical weather prediction models that assimilate a wide range of data types including direct (e.g., radiosonde) and indirect (e.g., satellite profiles) atmospheric observations in addition to ocean surface observations from ships. Lisan Yu, in International Geophysics, 2013 3.2.1 Atmospheric Reanalyses This is easily our favourite FLUX release so far.Simon A. This drop, part of the Photo Print series, is arriving in the US this week at adi retailers, including Oneness, before the Europe release in April. The satin upper gets drenched in tantalising breaking waves, while the sole, Three Stripes, heel cage and lining come up in white to provide some bright contrast. We've only scratched the surface on the awesome potential of this sneak though, and this 'Ocean Waves' edition continues to show us all-over prints may be the future of neck snapping. The adidas ZX Flux was an instantly impressive silhouette but things really got gobsmacking when the lightning print edition was revealed. Update: If you missed these over the weekend then fear not, Overkill has just scored a re-stock. UPDATE: Still one the best Flux combos we have seen so far, so much so we're giving these an additional run and fresh set of imagery as they start to pop up at select stockists stateside, including Sneaker Politics. ![]()
