Slide2 l.jpg

Cloud classification

High clouds (above 6km)

Cirrocumulus clouds – puffy, high clouds

Cirrus – thin, wispy

Cirrostratus – cover the sky. Can give us solar and lunar halos.



Slide4 l.jpg

Mid-level clouds (1.8 to 6 km)

Have prefix alto-

No halo

Altocumulus clouds

Altostratusclouds


Slide5 l.jpg

Low-level clouds (ground level to 1.8km)

Stratus clouds – low to ground, blanket-like

Nimbostratus – low clouds that accompany precipitation

Stratocumulus – low puffy clouds


Slide6 l.jpg

Clouds with vertical development

Cumulus clouds

Cumulonimbus clouds - thunderstorms


Slide8 l.jpg

Unusual cloud shapes

Lenticular altocumulus

Mammatus clouds

Fog – Moist air is cooled and condenses.

Advection fog – moist air moves over a cool surface.

Radiation fog – radiative heat loss cools the ground. Nearby air is cooled, leading to condensation. Morning fog is often radiation fog.

  • Lightning is touches an object rather than in the airdeadly!

  • Lightning Safety

  • Take shelter inside a building.

  • Do not use a land-line phone or electrical equipment like computers, etc.

  • Stay away as much as possible from anything that has pipes (sinks, bathtubs, showers, toilets).

  • DO NOT take shelter under a tree or the overhang of a tall building. Go inside.

  • If you’re on a lake, get to shore and find shelter immediately.

Watches and warnings l.jpg
Watches and Warnings touches an object rather than in the air

WATCH means conditions are right for weather to occur (thunderstorm, tornado, flood, etc). Be on the lookout.

WARNING means it is happening now, and you need to take shelter immediately.

Tornado safety l.jpg
Tornado Safety touches an object rather than in the air

If possible, get to an underground storm shelter.

Alternate shelter: small interior room on 1st floor with no windows (closet or bathroom)

If caught outside, get low in a ditch

Never stay in a mobile home.

Cars are nearly as dangerous as mobile homes.
