- Clouds jcan jbe jnormal jor jspecial. jThere jare jtwo jtypes jof jnormal jclouds.
- Cumuliform j(connective jclouds) jare jpuffy jand jassociated jwith jupdrafts
- Form jwhen jhumid jair jrises jthrough jcooler jair
- This jcan joccur jwhen jthe jair jat jthe jground jis jcolder jthan jthe jsurface
j(ex.

- Occurs jbehind jcold jfronts
- Clear jdays jwhen jsunshine jwarms jthe jearth jmore jthan jair
- Cold jair jblows jover jwarm jair jor jwarm jbody jof jwater
- The jbuoyancy jdrives jstrong jupdrafts
- There jare j4 jclassifications jby jvertical jdepth:
- Cumulus jhumilis j(small)
- Can jhave jturbulence jfrom jupdraft
- Cumulus jmediocris j(medium)
- Can jhave jturbulence jfrom jupdraft
- Cumulus jcongestus j(large)
- Poses jhazard, jthunderstorms jand jviolent jupdrafts
- Cumulonimbus j(thunderstorm)
- Poses jhazard, jthunderstorms jand jviolent jupdrafts
- Stratiform j (layer jclouds) jare jflatter jlike jsheets jor jblanket, jcan jextend jhundreds jof
