Why do we have seasons?
When the earth's axis points in a certin direction either away or towards the sun the weather or the season changes.
100
What is a flood?
A flood results from days of heavy rain and/or melting snows, when rivers rise and go over their banks.
100
When do tornadoes most likely to occur?
Any time of any day.

WHAT MAKES CLOUDS FORM RAIN?
Cloud drops form when warm air cools and the water in the air condenses.With lots of drops and movement (winds and currents) the drops bump and merge until heavy enough for gravity to pull out the drops as rain.

What is lightning?
Lightning is a bright flash of electricity produced by a thunderstorm.

WHY CAN YOU SEE YOUR BREATH WHEN ITS COLD OUTSIDE?
Your breath is reasonably warm and humid and it has invisible water vapor as a large component of the gas. Warm moist air meeting the cooler air outside the body causes the invisible water vapor to condense the cooler air outside are visible and form the cloud that you see.

What does FLOOD WARNING mean?
Flooding conditions are actually occurring in the warning area.
200
How does a tornado begin?
A tornado begins as a funnel cloud that has spinning columns of air.

Why are clouds white?
Clouds are white because of the reflecion from the sun.

How is hail made?
Hail is created when small water droplets are caught in the updraft of a thunderstorm. These water droplets are lifted higher and higher into the sky until they freeze into ice. Once they become heavy, they will start to fall. If the smaller hailstones get caught in the updraft again, they will get more water on them and get lifted higher in the sky and get bigger. Once they get lifted again, they freeze and fall. This happens over and over again until the hailstone is too heavy and then falls to the ground.

WHY ARE YOU LESS LIKELY TO SEE STATIC ELECTRICITY IN THE SUMMER?
In the summer, our dew points are much higher due to warm and humid air coming from the Gulf of Mexico and that is why we have humid weather.

What is the spanish word for tornado?
‘Tronada’

What is a cloud?
A cloud is a large collection of very tiny droplets of water or ice crystals. The droplets are so small and light that they can float in the air.

What is a supercell thunderstorm?
A supercell thunderstorm is a long-lived thunderstorm whose updrafts and downdrafts are in near balance.

WHY ARE YOU LESS LIKELY TO SEE STATIC ELECTRICITY IN THE SUMMER?
In the summer, our dew points are much higher due to warm and humid air coming from the Gulf of Mexico and that is why we have humid weather. In the winter, our dew points are much lower due to cold and direr air coming from Canada. The lower the dew point the better it is to create static electricity, so that's why you see it more in the winter.

About how big are raindrops?
They are smaller than a centimeter

Make a logical guess on how tornadoes stop.
It's unknown.

Why do clouds turn gray?
If the clouds get thick enough or high enough all the light above does not make it through, hence the gray or dark look.

What is ball lightning?
Ball lightning is a rare form of lightning. It usually appears as a reddish, luminous ball, but can come in any color. Ball lightning is usually spherical in shape and about one foot in diameter. Hissing noises originate from such balls and they sometimes make a loud noise when they explode.
500
HOW DO WE GET SNOW?
The water vapor in the clouds creates droplets and those droplets keep getting bigger and bigger until the fall. When temperatures get below freezing, it creates snow!
500
What is a flash flood?
A flash flood is sudden flooding that occurs when floodwaters rise rapidly with no warning within several hours of an intense rain.
500
Where are tornadoes most likely to occur?
The geography of the central part of the United States, known as the Great Plains, is suited to bring all of the ingredients together to forms tornadoes.
500
How are clouds formed?
All air contains water, but near the ground it is usually in the form of an invisible gas called water vapor. When warm air rises, it expands and cools. Cool air can't hold as much water vapor as warm air, so some of the vapor condenses onto tiny pieces of dust that are floating in the air and forms a tiny droplet around each dust particle. When billions of these droplets come together they become a visible cloud.

What is St. Elmo's Fire?
St. Elmo's Fire appears as a blue or greenish glow above pointed objects on the ground. It is created when tiny positively charged sparks reach up in response to negatively charges in the air or clouds above the ground. If a thunderstorm is nearby, St. Elmo's Fire might be seen right before a lightning strike.
