(3) Large-scale circulation at 500hPa height: the Asian zonal circulation in JJA is negatively
correlated with both the precipitation occurrence and severity. Another influential factor is the
Subtropical High in the Western Pacific (SHWP) in summer: the stronger the SHWP is the
larger the number of rainy days in North <strong>China</strong>.
(4) East Asian Summer Monsoon: A lower EAP (East Asian-Pacific Pattern) index, indicating
weaker East Asian monsoons, corresponds to less summer precipitation in North <strong>China</strong>. In
addition, when onset of South <strong>China</strong> Sea summer monsoon (SCSM) is early, the rainfall is rich
and persistent.

Abstract In this paper, 10 environmental data items including climatic and physical
variables for colza cultivation collected from 24 sample farmlands in Sabzevar township within
the period of agricultural year 2004-2005 and then required statistical analysis carried out for
the selected farmlands in order to select the significant linear multiple regression procedures
including enter, stepwise and backward in connection to colza yield . After selecting backward
procedure as the best model, four environmental condition variables including degree-day,
mean temperature, slope and EC of used groundwater extracted as necessary variables for
zonation of suitable areas in the whole the study area. <strong>The</strong>n the spatial maps of the selected
variables were prepared and the zonation map of suitable areas for cultivation of colza was
prepared using GIS functions. <strong>The</strong> results show that the appropriate regions for cultivation of
colza are located in the plain region in Sabzevar. Toward the border of the plain, suitability
conditions of colza cultivation is degrading. Keywords: Colza, Sabzevar, linear multiple
regression, Geographical Information System (GIS).

Field measurement data collected from the agricultural and meteorological test station of
CMA, 2004, was employed to investigate the energy balance problem during the entire corn
growing season. Analysis was performed for the entire growing season, 10-day, diurnal, and
