Cloud Formation• Clouds form when rising air is cooled below
its dew point
• Tiny particles called condensation nuclei in the air allow a cloud to form

Precipitation
• Rain and snow = most common forms of precipitation
• Drizzle is small raindrops that fall slowly
• It has to be 0 Degrees Celsius in order for it to snow.

Precipitation
• Sleet is a partially frozen mixture of rain and snow that occurs when the temperature is just above freezing
• Freezing Rain is super cooled rain that when it touches an object it freezes.

Precipitation
• Hail is in the form of ice balls, which usually occurs in violent thunderstorms– Hailstones begin as snowflakes that start to
melt and gather more moisture as they fall

Natural Hazards• Thunderstorms
– Most occur in the summer when the air is warm and moist
– Advancing cold fronts may push the warm air upward, causing the formation of giant cumulus clouds, and heavy precipitation
– Lightning, damaging hail, and tornadoes are possible
• Lightning strikes, flash floods and tornadoes spawned by thunderstorms cause about 100 fatalities per year in the US

Thunderstorms
• Thunderstorms damage• Flash Floods- sudden large movement of water
that can quickly wash away objects.• Winds – very strong winds• Hail – large hailstones can damage property • Lightning- can kill or damage anything it hits

Natural Hazards• Tornadoes
– Most common in the spring and early summer over the central US
– Are usually less than 0.3 miles (0.5 km) in diameter and usually last for 10 min or less
– Winds have been measured by radar in excess of 300 mi/hr

Tornadoes
• Tornadoes form from warm humid air masses that meet cold dense air
• Tornadoes become visible when it lifts up enough dust and debris from the ground.

Natural Hazards• Hurricanes
– Tropical depressions, areas of low pressure that usually develop in the late summer and early autumn in the Atlantic Ocean between South America and Africa
– When winds exceed 74 mi/hr the designation is changed from tropical storm to a hurricane
