Subtropical Rain - A Rainy Boxing Day

It has rained quite a bit and today its teaming. In subtropical climates the winters are relatively warm with hot and wet summers. Plants such as palms, citrus and broadleaf evergreens flourish here. Rainfall patterns resemble a more northern monsoonal 'wet' season with warm temperate conditions along the coastal strip in SE Queensland. Its interesting that rain plays a role in the hydrologic cycle. The earth is a 'losed' system, like a bubble, and there is as much water on the plantet as there ever has been or ever will be, this never changes. (barring a cataclismic event:-) Moisture from the oceans and water evaporates and vapor from plant respiration rises, condenses into drops, falls from the sky, and eventually returns to the ocean via rivers and streams to repeat the cycle again. So pherhaps molacules of water you drink from a glass of water could have been anywhere in the world at some time.
