Ravi,

1  y and x

  double y(y=337);
     :units = "km";
     :long_name = "y coordinate of projection";
     :standard_name = "projection_y_coordinate";
     :grid_spacing = "13.545 km";
     :_CoordinateAxisType = "GeoY";

 data:

  {-588.8927377703312, -575.3477377703313, -561.8027377703312, 
-548.2577377703312, -534.7127377703313,....

  double x(x=451);
     :units = "km";
     :long_name = "x coordinate of projection";
     :standard_name = "projection_x_coordinate";
     :grid_spacing = "13.545 km";
     :_CoordinateAxisType = "GeoX";

 data:

  {-3332.1553367171628, -3318.6103367171627, -3305.0653367171626, 
-3291.5203367171625,...


To convert the y and x to Lat/Lon the model needs to be opened as a 
GridDataset, or the FeatureTypes tab in ToolsUI. Here's an url:

http://www.unidata.ucar.edu/software/netcdf-java/tutorial/GridDatatype.html
also look at:
http://www.unidata.ucar.edu/software/netcdf-java/v2.2.22/javadoc/ucar/nc2/dt/GridDatatype.html

2. hybrid represents vertical pressure coordinates. 

I'll try to get some code out tomorrow to show you how to get the information.
