Wind in the atmosphere and currents in the ocean are caused by uneven heating that produces convection the coriolis effect transpiration conduction

Convection : Warm air rises and cold air sinks, you have a cycle there :D
You can experience it on the beach shore. Since water has a high heat capacity ( it takes longer to heat up ) and the sand get hot quickly, the air on the shore gets warm and rises. When the air reaches to certain elevation (or meet the temperature of the beach), it gets cooler and sinks, cold air from the beach blown to the shore. 

Since a female is both xx chromosome and the male passes down the x chromosome, than the offspring would be female since a female is xx.
