Hello to everybody!

I am a new subscriber to MET-AI, and this message is to introduce 
myself to the rest of the subscribers, following the  suggestions 
of the list owner, though I must stress that I am a very beginner 
in  the AI fields, my joining to MET-AI been a way to  know  more 
about  the  techniques and their meteorological  applications.  I 
have   been  using  multivariate  statistical  tools   (Principal 
Components  and  Multiple  Regression Analysis)  since  my  Ph.D. 
thesis,  in  1986, but last year I become  interested  in  neural 
networks as a way to account for non-linear dependencies  between 
variables.

Name: Jose Antonio Guijarro.

Organization:   Centro  Meteorologico  de   Baleares   (Instituto 
Nacional de Meteorologia, Spain).

Interests:   Statistical   applications   to   Meteorology    and 
Climatology.

Projects/systems: 

    Name: Statistical tools for local operational forecasts.
    People involved: J.A.Guijarro and J.Gonzalez (meteorology).
    Description:   Gathering  information  from  our   rawindsond 
    station  for  the last decade, we have begun  by  deriving  a 
    Multiple Regression model to forecast extreme temperatures in 
    several  sites  of the Balearic Islands. The  forecasting  is 
    performed through application of the model to the independent 
    variable  values  forecasted by the ECMWF  for  our  location 
    (Perfect  Prog scheme). Next steps will involve extension  of 
    the  model to forecasting other variables  (rainfall  amounts 
    and probability, thunderstorms and associated severe  wether, 
    etc) and trying AI tools to improve the models.

    Name: Climatological Atlas of the Balearic Islands.
    People involved: J.A.Guijarro (meteorology).
    Description:  Developping  statistical models  for  automated 
    mapping of several climatic elements. The models used so  far 
    are  again regression models between the  climatic  variables 
    and  physiographic  predictors such as  altitude,  slopes  in 
    different   directions,  distance  to  the  sea,  etc.   More 
    physically based predictors will be tried in the future,  and 
    AI tools may prove also very useful.
