New weather forecast system makes predictions faster and more accurate

Increasing horizontal resolution in numerical weather prediction and climate simulations: illusion or panacea?

The steady path of doubling the global horizontal resolution approximately every 8 years in numerical weather prediction (NWP) at the European Centre for Medium Range Weather Forecasts may be substantially altered with emerging novel computing architectures. It coincides with the need to appropriately address and determine forecast uncertainty with increasing resolution, in particular, when con...

Assessing parametrization uncertainty associated with horizontal resolution in numerical weather prediction models.

The need to represent uncertainty resulting from model error in ensemble weather prediction systems has spawned a variety of ad hoc stochastic algorithms based on plausible assumptions about sub-grid-scale variability. Currently, few studies have been carried out to prove the veracity of such schemes and it seems likely that some implementations of stochastic parametrization are misrepresentati...

Might Makes Right or Right Makes Might

In a path-breaking article, Wade Huntley (1996) reinterpreted Immanuel Kant’s pacific union as a systemic phenomenon. Huntley’s argument spawned a new wave of inquiry into the evolutionary expansion of the democratic peace, with several empirical studies finding a positive relationship between global democracy and systemic peace (e.g. Crescenzi and Enterline 1999; Gleditsch and Hegre 1997; Kade...

DNA Makes RNA Makes Innate Immunity

Microbial DNA in the cytosol induces production of interferon-beta (IFN-beta) and an innate immune response. Chiu et al. (2009) now implicate cytosolic DNA-dependent RNA polymerase III as the DNA sensor linking DNA release by pathogenic bacteria and viruses in the host cell cytosol to IFN-beta production and innate immunity.
