# A typical distance for rain to fall is about 6,500 feet. A typical maximum size for a raindrop is 1/3 to 1/5 of an inch in diameter, since above that diameter wind force will tend to break it up into smaller droplets. A one fifth inch diameter raindrop weighs 0.002 ounces and has a terminal velocity of about 22 miles per hour. For comparison, the water from a typical garden hose has a water pressure of 40 psi above atmospheric pressure, which can propel the water to a velocity of around 35-36 miles per hour. 

# The least rainy place on earth isn’t in the desert. Antarctica gets only 6.5 inches of rain or snow per year, making it the continent with the lowest annual rainfall by far. On the other end of the spectrum, Lloro, Colombia averages about 534 inches (44.5 feet) of rain per year. 

# In Cherrapunji, India the weather station there holds the world record for the heaviest 48-hour rainfall (more than 98 inches – over 8 feet), set in 2014. # In Cherrapunji after a rain there is a smell called petrichor. The average raindrop hits a porous surface of the ground with enough force to trap air bubbles at point of impact. The bubbles then rise and pop, releasing aerosols. 

# Rain sometimes evaporates before it hits the ground. It's known as phantom rain or virga. You will see curtains of rain dangling in the sky while the ground remains dry. # You will get less wet in the rain if you run. 

# Generally speaking, if you see a cumulonimbus cloud—a tall, puffy cloud that looks flat at the top— or a nimbostratus cloud, a flat low-level gray cloud—you can be fairly certain that rain is in the 24-hour forecast. # Raindrops do not have a teardrop shape. Their size varies and the smallest raindrops are called cloud droplets, and their shape is round. Big raindrops are shaped like parachutes. The biggest raindrops on Earth were recorded in Brazil and the Marshall Islands in 2004— some of them were 0.39 inches in diameter. 

# In some places unusual things have been known to fall from the sky, like small fish in addition to other things. 

# The weight of rain is substantial; an inch of rain on an acre of land weighs roughly 226,000 pounds

# Rain droplets contain dissolved nitrogen in the air and it makes the grass look greener after rainfall. 

# Mount Waialeale in Kauai, Hawaii, as it has up to 350 rainy days per year. # A 2016 study determined it’s also possible to measure rainfall amounts over oceans by monitoring the sound of droplets hitting the waves. 

# Florida, Louisiana and Alabama were the wettest states, while California, Montana, Nevada and Arizona were the driest (Las Vegas took the top spot for driest city). 

# Las Vegas is the only large US city to average less than an inch of rain for every month of the year. At its driest, Las Vegas hasn't even accumulated an inch of rain throughout an entire year. The driest year on record for Las Vegas was 1953, when 0.56 inches fell at the airport. When a rain cloud does pass over Las Vegas, it usually drops less than one-tenth of an inch and seldom does the city get more than half an inch of rain in one day 

# The wettest US cities are: Portland, Oregon. Average annual rainfall: 43 inches with the average rainy days per year being 154. It's followed by: Seattle, Washington, Tallahassee, Florida, Port Arthur, Texas, Miami, Florida, Baton Rouge, Louisiana, West Palm Beach, Florida and New Orleans, Louisiana. 

     Weather can make one person cheery and another to feel grumpy. Now research suggests we are hard-wired in how we respond to weather. Scientists have identified four personality types based on how weather affects a person's frame of mind. Weather personality types appear to run in families. Whether this is due to genetics, or just a parent's attitudes rubbing off onto their children could not be determined. Nevertheless, this finding bolsters the theory that for many people weather and mood are strongly linked. 

Fair Weather - Warm, sunny weather brings out the best in you. Clear skies put you in good spirits. You feel happier, less fearful and less angry on days with more sunshine and higher temperatures. While sun and temperature affect you most, you also respond to rain. Ongoing rainstorms will dampen your spirits.
Cool Cloudy – This is where some people thrive and a little rain boosts their mood. Once it turns warm and sunny they get grouchy, become unhappy, fearful and angry. 
 Rain Haters — Rain really bothers them. Wet weather disturbs them far more than it influences other weather personality types. Rain leaves them feeling unhappy, anxious and most of all, angry. The main good mood driver is lack of rain. 
Unaffected — Rain or shine, hot or cold, these people are little affected by the weather. Even then, they might feel a little more anxious than normal on the cooler, cloudier days.
