The weather is influenced by terrain, season, altitude, and latitude, as well as by climate. Weather forecasting is now done using powerful computer analysis but there are many natural clues that will help you to interpret the weather. Looking to windward, clouds can help you predict weather changes coming your way.
Kinds of clouds
Clouds are classified by height and appearance. There are three kinds: low, medium and high.
Cirrus: High, wispy clouds that indicate far weather. In winter cirrus with steady wind may herald snow.
Cirrostratus: High, dark streaks of clouds that may warn of rain or snow within next 15 hours.
Cumulonimbus: The dark, flat-topped anvil-shaped head is associated with heavy rain.
Stratocumulus: Irregular shapes of dense grey or white cloud rarely produce more than light drizzle.
Cumulus: Drifting puffs of white Cumulus clouds against a blue sky forecast fair weather.
Stratus: Low, shallow grey clouds produce long periods of drizzle, Cold winds can increase the precipitation.
Altostratus: Thick grey clouds that may give rise to the first drops of rain.
Red or Orange Sky: A red or orange sky in the evening indicates the approach of fair, sunny weather. However, a red or orange sunrise suggests rain or snow within a day.
Rainbow: A rainbow early in the morning signals showers. A rainbow late in the day heralds fine weather. |
