Is there a way to find the speed rain falls by its streak pattern on a car window?

This is complicated! I am not good at this but just think:\neven the angle of the rain drop is too complicated! It can be affected by the speed of the wind, the size of the droplet, the altitude (maybe?), etc., etc.\nNow if the glass is full of dirt that will hold the droplets, or the glass is coated with something slippery, then the speed will be affected, too.\nIf the air is so polluted, the rain is acid, then ... \nAnd there could be more factors....

double_nubbins has the right approach.  I will add a couple of hints: how long will it take the car to fall 19ft (remember the acceleration equation s=.5*g*t^2).  Assuming there is no air drag, the horizontal velocity of the car must be enough to cover the 52m width in that time.\n\nSpeed of the car? The horizontal speed? The falling speed?  The speed in the direction of motion?\n\nHorizontal speed: as calculated above\nFalling speed = g*t, where t is the time calculated above.\nSpeed  in the direction of motion = sqrt(horiz speed ^2 = falling speed ^2)

This is a challenging question. There are weather ships that try to measure wind speed, but of course the presence of the ship itself can produce orographic effects and produce biases. Another estimate can be made from satellite and airplane observations of cloud movement. Another technique is to fly balloons (radiosondes) up into the air column and use anemometers on the balloons to measure wind speed, or track the balloons using radio methods and try to infer wind speed from that. Dropsondes can be dropped from airplanes as well to estimate windspeed. \n\nA technique that is used from satellites and airplanes is to measure the roughness of the sea surface by boucing microwaves off it (a "scatterometer"). The windier it is, the rougher the sea surface. \n\nThere are probably other techniques that are in use or have been tried or at least considered as well\n\nProbably there is room for improvement in all of these, if you are so inclined to think about it!

Each drop of rain, or snowflake, carries a very tiny electrical charge as it falls.  When you get a concentrated amount of rainfall or snowfall in a local area with a lot of updraft/downdraft activity, as with a cumulonimbus cloud, whose height can top 60,000 feet, there is a large amount of electrostatic charge that builds up between the cloud and the ground, and also from cloud to cloud.  When the charge is huge enough to overcome the dielectric resistance of the air between, there's an arc, or discharge, of that static electricity, visible as lightning.  The thunder is the sound of that huge spark as it jumps the gap.  Since sound travels only about 760 MPH through air (approx. 1100 ft / sec), while light's speed 186000 MPS is so much faster, the delay in hearing the thunder is a good approximate indicator (in fifths of a mile), of how far away the lightning strike was.

I think weatherbug is for windows only at the moment.\n\nI use firefox with the forcastfox extension.

Imagine a `speed` x `time` chart. Plotting the data, we will have parallelogram whose area will the length the car walked between the two speeds.\n\nWe'll have, then, 30*((5.56+13.89)/2) = 291.75m

the rain is measured in a rain gauge.  The wind is measured by a anemoter(i could have spelled it wrong), and the temperature is measured by a thermometer.  None of that stuff is expensive.  I bought something with a rain gauge and a thermometer all in one and i paid like 10 dollars.  I am not sure how much an anometer costs though.  I hoped i helped ya.

It measures the density of cumulative clouds. Good Luck !  :)

If you mean how can we forecast the weather, it's largely a matter of  measuring teh movement or change of wind currents, humidity, and a number of other factors.  Now, most of that is fed into a computer, and it gives aprediciton of what the weather will be over a short period of time.  Or, you could use an ancient Indian weather rock:  If it's hot, the sun is out; if it's wet, it's raining; if it's swinging, the wind is blowing...

by the effect of wind.\n      the rain comes from too height & there the speed of air is very fast 'n' due to it the angle deflected.this deflected angle is very short but the height is too large so it seems like a big deflection.

I take it you are reading your data that is taken from  GPS system. if so you should be able to get a latitude and longitudinal positions of a car in which case mapping that should not be very hard.\n\nhttp://gpsdrive.kraftvoll.at/changes.shtml
