The water cycle never concludes but meteorogical
patterns sometimes shift
An area may have too much precipitation and flood one year
The next year there may be a drought with minimal or no precipitation

Changes in one place can transfer into changes in neighboring locations
It is like tossing a rock into the water making ripples that spread out
