| Wind
is the motion of air relative to the surface of the Earth and is one
of the most highly variable climatic elements, both in speed and direction.
The general wind patterns are defined by the atmospheric pressure distribution,
but locally the wind can be strongly affected by several factors, including:
|
|
|
The
time of day (e.g. sea breezes) |
|
|
Height
above the ground |
|
|
The
surrounding terrain |
|
| For
this reason care should be taken when interpreting the wind speed and
direction data provided by the SILO meteograms. |
| The wind direction is specified relative to true (geographic) north, and is the direction from which the wind is blowing. The direction can be specified either as the number of degrees clockwise from true north, or as one of the 8 or 16 compass points. Within Australia wind speeds are generally presented in kilometres per hour. For nautical use the wind speed is measured in knots, while for some scientific applications units of metres per second are used. |
