Q:

How can I find weather data for greenland sea during the 4 seasons?

In the Greenland Sea or in Denmark's strait, near greenland's cost, 
how can I find weather information for this place? Specifically, with respect to months (i.e, dec-feb, march-may, june-august, oct - nov). When it is warmest, coldest, etc.

A:

An interactive website called earth has detailed weather data for the entire globe. Using this is similar to using Google Earth. You can adjust it for almost any weather data you need by clicking the "earth" icon and adjusting the date under each section. You can see the numerical data for a specific area by clicking the area on the globe with your mouse.

A:

You can try the CFSR, a model reanalysis of climate, from 1979 to 2010, or you could use model data, such as the GFS for more recent data inquiries.
CFSR: ftp://nomads.ncdc.noaa.gov/CFSR/HP_time_series/
GFS: ftp://nomads.ncdc.noaa.gov/GFS/Grid4 
The data is in a very raw format (called grib/grib2), that I'd do some research on before you use this data.
