“…This is the so-called nudging nesting, of which two versions are available. The 3-D analysis nudging introduces a Newtonian relaxation term into the prognostic equations of the model, and was first introduced by Charney et al (1969). This addition corrects some variables by an artificial tendency term based on the difference between the original state produced by the model and the driving data set (Lo et al, 2008).…”

“…Consequently, an understanding of the manner in which atmospheric variables mutually interact has proven extremely useful in atmospheric dynamics and especially in numerical weather analysis and prediction (e.g., Smagorinsky et al 1970;Daley 1991). For example, based on geostrophic adjustment theory, Charney et al (1969) sought to assess the impact of satellite-derived temperature observations on the initialization of a global circulation model under the assumption that temperature and pressure are related hydrostatically. Using simulated data, they found that the large-scale wind field may be inferred from a pseudo-satellite-derived temperature profile if surface pressure is known, and that inserting temperature corrections into a model at 12-h intervals can significantly improve the forecast.…”

“…При анализе состояния атмосферы широкое распространение получила схема циклического усвоения данных, предложенная еще в работе [Charney et al, 1969]. В цикле последовательно выполняются краткосрочный прогноз с заблаговременностью несколько первых часов и анализ состояния атмосферы.…”
