To all of you who are into physical science and all that.

I have a homework question that I really need help on. Ok here it is,
How does Bernoulli's principle help explain weather? With examples such as
-Wind
-Airmasses
-Fronts
-High/low pressure systems.
I have no idea and I have looked every were for an answer.
Please help.

Lets first look at Bernoulli's Principle:

"In fluid dynamics, Bernoulli's principle states that for an inviscid flow, an increase in the speed of the fluid occurs simultaneously with a decrease in pressure or a decrease in the fluid's gravitational potential energy."

"Bernoulli's principle is equivalent to the principle of conservation of energy. This states that the sum of all forms of mechanical energy in a fluid along a streamline is the same at all points on that streamline. This requires that the sum of kinetic energy and potential energy remains constant. If the fluid is flowing out of a reservoir the sum of all forms of energy is the same on all streamlines because in a reservoir the energy per unit mass (the sum of pressure and gravitational potential ρgh) is the same everywhere."


What do you think your question is trying to ask in relationship with what Bernoulli's Principle represents?

OK that makes sense thanks. But one question What does inviscid flow mean?

in·vis·cid (n-vsd)
adj.
1. Having no viscosity.
2. Physics & Chemistry Of or relating to a fluid with no viscosity.

OOOOOOOOH now i get it.
