do leaves turn upside down when rain storm is coming?

Yes, I have seen that happen for years. Sycamore especially. The wind blows them in a twist. I don't know the involvement with the water, but when it rained it usually blows first and that's when you see the leaves twist over...

Yes, it's common for raindrops to collide after they start to fall. The more wind there is the more collisions are likely.

it does not predict the weather....but if you have a storm moving in...the direction the storm is moving makes a difference

Although the earth is rotating in the same direction the angle of incidence is the opposite of that in the northern hemisphere. as the earth rotates the angular momentum causes the water to spin. Think about wheels placed against the surface of the earth and angled so that their axles are pointing at the center of the planet as the earth rotates they will turn in opposite directions.

Direction doesn't matter so much as "orientation".  Many seeds have an up, and a down.  If you plant them the wrong way up, it doesn't really matter except that the stem growth will come out and have to "go around" the rest of the seed to head upwards and out towards the sun.  This uses up some of the energy stored in the seed, so that plant might not do as well as one planted with the right orientation.\n\nhope this helps...

Their roots are actually specialized branches (rhizoids) that grow in the ground or into tree bark, on rock, etc. so the whole plant is actually living sideways.  The branches absorb water just like roots would. They have a great capacity for storing water, and most are pretty small, so they don't need as much rain as most plants, just humidity/moistness.  Most surfaces are wet with dew in the morning, and they absorb this.

They use a ouiji board.\n\nNot hard to predict snow, sleet, and hail in Winter and rain, wind, and thunderstorms in Summer.  Nice to throw in sunny or cloudy.\nThere are only so many different weather results.

Rain forces down cooler air from the atmosphere.

I'm not completely sure, but I do know that the ring signals that the next day will be rainy. Perhaps it has something to do with an incoming front. Or a rise in humidity.

For the most part, yes. Low pressure systems in the Northern Hemisphere spin counterclockwise and Highs spin clockwise. The reverse is true in the Southern Hemisphere.

yes.\n\nAt least the great majority of tornadoes rotate counterclockwise \n(as do all low-pressure systems) in the northern hemisphere, and clockwise in \nthe southern hemisphere, for the reason (coriolis force) given by Eric \nPeterson in response #1.  But occasionally, it would seem, northern hemisphere \ntornadoes do rotate clockwise:  S. Flora's book "Tornadoes of the United \nStates" cites an 1890 article in the American Meteorological Journal.  Its \nauthor, a J.P. Finley, states that, of 550 American tornadoes he studied, 29 \nwere deemed to have rotated clockwise.  I have not been able to find any \n"modern" study of this question.  But I believe it could be true. The region \nof swirling air that contracts to become the tornado is not itself large \nenough in extent to have its rotation dictated by the coriolis force; rather, \nit "inherits" this tendency from the great masses of air whose movement sets \nthe stage for the storms and any associated tornadoes. If the study cited is \ncorrect and representative, on occasion the direction of rotation is set by \nsome other factor, perhaps the topography in the area where the tornado forms, \nfor example.

So the rain dosent get confused

Yes.  There is a special anomaly called a temperature inversion, which happens in special circumstances, particularly right after sunrise.   The inversion part refers to when it does not necessarily go from hot-to-cold, starting from the surface of the earth on outward.  Sometimes it's the reverse.  It happens because the air above ground is being warmed up before the sun rises high enough to start getting infrared heat to hit the ground.

do you mean adiabatic rainfall

The shape and direction of the twist is given by Coriolis effect, which  says since everything is falling to the center of earth, and it is spinning, there developes a curve, just like the one you see on your toilet, as opposite of the one you'd see in other toilet in southern hemisphere (if you are in the northern one)

The only thing is, they don't always lie down when it is going to rain.  A lot of times you see them standing in a tight bunch right before it rains, too.  They almost always have their rear ends to the wind.  A lot of the "old timers" had ways of predicting the weather just by looking at natural things, guess this was just one of them.

The sun will rise and it will rain somewhere.
