WEATHER

2. A line connecting equal points of pressure.
5. A prefix to cloud-type names for clouds generally found between 3000 and 7000 meters. Alto comes from the Latin word meaning "middle".
6. A calendar that uses astronomical information and weather data. Almanacs list tide data, give the positions of the stars and forecast weather each day.
8. A high-pressure system that moves in a clockwise motion. These bring you sunny skies.
9. The position of the Earth’s surface north or south of the equator.
11. Air An air mass that originates over Canada and brings us cold temperatures.
14. The position of the Earth’s surface east or west of the Greenwich meridian.
15. Pressure The weight of air pressing down on earth. Air pressure can change from place to place, and this causes air to move, flowing from areas of high pressure toward areas of low pressure. It’s the same as barometric pressure.

1. Water droplets so small that they are floating in the air. Because mist droplets do not fall, mist is a type of fog.
3. The season of the year that occurs after summer and before winter. Autumn officially begins in late September.
4. A forecast issued by the National Weather Service to highlight conditions that require caution, but are not thought to be immediately life threatening.
5. Clipper A fast-moving low pressure system that occurs during the winter and sweeps southeast from Alberta, Canada, across the northern Great Plains and Midwest of the United States. These storms usually bring a few inches of snow.
6. A large body of snow, ice or rock and debris sliding down a mountain. Worldwide, about one million snow avalanches occur per year.
7. A layer of gases surrounding a planet. The Earth’s atmosphere is divided into five layers: exosphere, thermosphere, mesosphere, stratosphere, and troposphere.
8. A weather instrument that measures the wind speed.
10. A water substance in the solid phase.
12. An intense winter storm with winds of 35 m.p.h. or higher with falling and/or blowing snow to reduce visibility below 1/4 mile for at least three hours.
13. Borealis It’s often called the "northern lights". It occurs 50 to 100 miles above the earth, when energetic particles from a solar storm cause the gases in the upper atmosphere to glow. Auroras can last between a few minutes to several hours. It’s common across Alaska and northern Canada.
