Query: Forecast of surface layer meteorological parameters at Cerro Paranal
  with a mesoscale atmospherical model   This article aims at proving the feasibility of the forecast of all the most
relevant classical atmospherical parameters for astronomical applications (wind
speed and direction, temperature) above the ESO ground-base site of Cerro
Paranal with a mesoscale atmospherical model called Meso-Nh. In a precedent
paper we have preliminarily treated the model performances obtained in
reconstructing some key atmospherical parameters in the surface layer 0-30~m
studying the bias and the RMSE on a statistical sample of 20 nights. Results
were very encouraging and it appeared therefore mandatory to confirm such a
good result on a much richer statistical sample. In this paper, the study was
extended to a total sample of 129 nights between 2007 and 2011 distributed in
different parts of the solar year. This large sample made our analysis more
robust and definitive in terms of the model performances and permitted us to
confirm the excellent performances of the model. Besides, we present an
independent analysis of the model performances using the method of the
contingency tables. Such a method permitted us to provide complementary key
informations with respect to the bias and the RMSE particularly useful for an
operational implementation of a forecast system.
