Study Notes
Weather Basics
- Definition: Weather refers to the atmospheric conditions at a specific time and place.
-
Elements of Weather:
- Temperature
- Humidity
- Precipitation
- Wind speed and direction
- Atmospheric pressure
Tornadoes
- Definition: A tornado is a rapidly rotating column of air that is in contact with both the cloud base and the surface of the Earth.
-
Formation:
- Requires warm, moist air at the surface and cold, dry air aloft.
- Often forms in severe thunderstorms (supercells).
- Wind shear (changes in wind speed/direction) helps create rotation.
Tornado Characteristics
- Appearance: Funnel-shaped cloud descending from a thunderstorm.
- Scale: Measured using the Enhanced Fujita (EF) Scale, ranging from EF0 (weak) to EF5 (violent).
- Path Length: Can vary from a few yards to over 100 miles.
- Duration: Typically lasts from a few minutes to over an hour.
Tornado Safety
-
Before:
- Monitor weather alerts and forecasts.
- Identify a safe place (basement, interior room, storm shelter).
-
During:
- Go to the designated safe area immediately.
- Avoid windows and cover yourself with something protective.
-
After:
- Stay alert for additional storms.
- Be cautious of hazards such as downed power lines or debris.
Tornado Climatology
- Occurrence: Most common in the United States, particularly in "Tornado Alley" (e.g., parts of Texas, Oklahoma, Kansas).
- Seasonality: Peak tornado season in the U.S. is typically spring, but can occur year-round.
Key Facts
- Tornadoes can produce winds exceeding 300 mph.
- The average tornado travels approximately 3-5 miles before dissipating.
- Tornado warnings are issued when a tornado is sighted or indicated by radar.
Weather Basics
- Weather represents the atmospheric conditions specific to a time and location.
- Key elements affecting weather include:
- Temperature: Measures heat energy in the atmosphere.
- Humidity: The amount of moisture present in the air.
- Precipitation: Any form of water that falls from clouds, including rain, snow, sleet, or hail.
- Wind Speed and Direction: The movement of air relative to the ground.
- Atmospheric Pressure: The weight of the air above a given point, influencing weather patterns.
Tornadoes
- A tornado is characterized as a rapidly rotating air column in contact with both the cloud base and the Earth's surface.
- Formation requires specific atmospheric conditions:
- Warm, moist air at the surface interacts with cold, dry air above.
- Typically arises within severe thunderstorms known as supercells.
- Wind shear, involving changes in wind speed and direction, plays a crucial role in rotation development.
Tornado Characteristics
- Tornado formation presents as a funnel-shaped cloud extending from a thunderstorm.
- Intensity is measured using the Enhanced Fujita (EF) Scale, which ranges from:
- EF0: Weak tornadoes with minimal damage.
- EF5: Violent tornadoes that can result in catastrophic destruction.
- Path lengths of tornadoes can range from a few yards to over 100 miles.
- Average duration of a tornado varies, usually lasting from a few minutes up to an hour.
Tornado Safety
-
Before a Tornado:
- Monitor weather updates and alerts for tornado warnings.
- Identify and prepare a safe location such as a basement or interior room.
-
During a Tornado:
- Move to the designated safe area immediately and stay away from windows.
- Protect yourself with heavy blankets or similar objects.
-
After a Tornado:
- Remain vigilant for further storms and alerts.
- Exercise caution around potential hazards like fallen power lines and debris.
Tornado Climatology
- Tornadoes predominantly occur in the United States, especially within "Tornado Alley," which includes parts of Texas, Oklahoma, and Kansas.
- Tornado activity peaks in the spring, but they can occur throughout the year.
Key Facts
- Tornadoes have the potential to produce winds exceeding 300 mph, causing significant damage.
- An average tornado travels a distance of approximately 3 to 5 miles before losing intensity and dissipating.
- Tornado warnings are issued based on visual sightings or radar indications of tornado activity.
