Special Issue Information

Dear Colleagues,

The emergence of the Earth Modeling System paradigm in the early 2000s, epitomized by the Integrated Forecast Systems, has led to the coupling of atmospheric dynamics with the equations describing transport of reactive tracers. The modern air quality prediction systems are, in fact, weather forecast models with a significantly expanded suite of the parameterizations including chemistry, surface exchange process and convective mixing. This advancement creates an unprecedented potential to increase the realism of computer simulations, superior to those from the previous generation of the chemical transport models. At the same time, the new paradigm of air quality prediction requires better chemical kinetics schemes and more realistic models of the aerosol dynamics. Furthermore, coupling of the processes with vastly different space and time scales within a single model demands the accurate mass conserving, non-oscillatory advection scheme as well as the new time stepping algorithms.

Contributions are being sought to document the current status of modern air quality prediction. The most relevant papers are those discussing the following subjects:

  • Strategies of coupling between the atmospheric chemistry and the numerical weather prediction models including description of the actual air quality prediction systems.
  • Are the off-line models still relevant in the air quality prediction?
  • The interaction between air quality prediction and traditional parameterizations of the numerical weather prediction models.
  • The discussion of chemical kinetic schemes for use with air quality prediction models.
  • New methods for modeling of the aerosol dynamics.
  • Numerical schemes for solving the reactive transport with stiff chemical interactions.
  • Data assimilation algorithms for the air quality prediction.
  • Studies illustrating the interaction between weather and aerosol processes.
  • Studies of small scale flows and their role in the air quality prediction.
  • The evaluation of predictability limits for air quality forecast.

Blocking weather patterns cause persistent weather situations that alter typical wind and circulation patterns which may result in stagnant weather conditions at the surface and potentially adverse conditions that affect society, such as extended warmth, drought, precipitation or fog. One problem that may develop is adverse concentrations of air pollutants in populated regions that may persist for several days or longer. This study looks for possible correlation between blocking patterns and air quality episodes in southern Ontario, Canada. The method used was examination of various cases of air quality episodes. The meteorological details of these examples were examined to determine possible correlations with blocking patterns. Results of the comparisons revealed that various types of blocking patterns correlated with worsening air quality episodes in various regions of southern Ontario. The conclusion is that some large-scale as well as regional-scale blocking patterns may cause adverse air quality in different cities or regions of the province during any month, and forecasters need to be vigilant for these patterns.
