The long term average being 30 years. These weather variations are affected by the temperature, precipitation, and wind.
Climate determinants include latitude, altitude, proximity to mountains and oceans, proportion of land to water, thermohaline circulation of the ocean, ocean currents, density and type of vegetation present in an area, as well as the areas' water retention and rainfall.
<span>Climate are classified into three groups. These are Bergeron and Spatial Synoptic, Koppen, and Thornthwaite.</span>
(1) Meteorological/Climate factor:
-Rainfall intensity
-Rainfall amount
-Rainfall duration
-Distribution of rainfall over the drainage basin.
(2) Phsyiographic factors (e.g. watershed)
- watershed size
-Watershed shape
-watershed slope
(3) Vegetation
- Dense vegetation leads to less run-off while sparse vegetation leads to more run-off.
(4) Urban development.
- Roads and buildings have do not allow infiltration into the soil. Water will therefore run off directly into the stream, at a very fast rate and in significant volume.
