drawmeridians

drawmeridiansは、経線（子午線）とそれに対応する軸ラベル（緯度の数値）を描く。

線無しで、軸ラベルのみを書くためには

map = Basemap(projection='cyl',llcrnrlat=-90.0,urcrnrlat=90, \

llcrnrlon=0.,urcrnrlon=360.1,resolution='c') #Equidistant CYLindrical Projection

map.drawmeridians(np.arange(0.,361.,120.),labels=[0,0,0,1],fontsize=10,linewidth=0.0)

軸ラベル無しで、線だけ描くには

map.drawmeridians(np.arange(0.,361.,120.),labels=[0,0,0,1],fontsize=10,linewidth=0.0)

緯線を描く関数は，drawparallels．

drawmeridians draws the meridian and the corresponding axis label (numerical value of latitude).

You can draw only the axis labels, without lines by

map = Basemap(projection='cyl',llcrnrlat=-90.0,urcrnrlat=90, \

llcrnrlon=0.,urcrnrlon=360.1,resolution='c') #Equidistant CYLindrical Projection

map.drawmeridians(np.arange(0.,361.,120.),labels=[0,0,0,1],fontsize=10,linewidth=0.0)

You can draw only lines, without the axis labels by

map.drawmeridians(np.arange(0.,361.,120.),fontsize=10)

"drawparallels" function draws the meridians.
