The water vapor brought by SW air current in the drought year on each level of troposphere was less than that in the rainy year.
For the reason of growing in rainy season spring maize need one time of irrigation, sunflower need twice (105-110mm each) in dry years, but no need in rainy years.
As it happened to be a rainy year, I was often disturbed by the pitter-patter of rain beating down against the window and roof.
