Adelaide Weather Charts
-
Thunderstorm Potential
An index using a combination of outputs to determine areas where thunderstorms are possible, likely, or potentially severe.
-
-
MSLP and Rain
Mean Sea Level Pressure weather map in hectopascals (hPa) along with rainfall accumulation in millimetres forecast for the 3 hours up to chart time.
-
Temperature
Air temperature in degrees Celsius at the surface layer, which is representative of the temperature a person may experience outdoors.
-
Winds and Streamlines
A measure of the average air speed in knots. 10 metres is used as it's just above local interference from structures and trees. Streamlines show the origins of that air mass.
-
Lifted Index
A measure of atmospheric instability which indicates where thunderstorms may develop. The lower the negative number the greater the instability and possibility of thunderstorms.
-
CAPE
Convective Available Potential Energy (CAPE) is a measure of instability. Higher values, particularly over 1000 indicate greater potential for thunderstorms or severe thunderstorms to develop.
