Reading a Wind Vane (4.4.6)

Thank you for visiting. This topic is currently incomplete.

This article applies to versions 4.4.6 and later of P2 Explorer. See Release History for more.

The Wind Vane shows you when the wind direction approaches a direction that may be considered problematic, such as emissions drifting too closely to a settlement.

At any time, you can hover over the wind vane to see the actual reading for:

• Current wind direction
• Average wind direction
• Minimum wind direction
• Maximum wind direction

Ordinarily, the wind vane has a transparent background with grey shaded zones. The shaded zones represent 'danger' and 'warning' zones.

Additionally, the wind vane contains a blue semi-circle divided in two, representing an average wind direction, as well as maximum and minimum directions. These are usually used to indicate the prevailing winds.

Note: The colours shown here refer to the default style for the wind vane. Colours are configurable during page design so may be different from site to site.

Danger Zone

The 'danger' zone indicates the wind is blowing in a direction that is considered to be a problem.

When the wind direction is within the darker 'danger' zone, the zone and outline of the wind vane change to red.

Warning Zone

The 'warning' zone indicates the wind is blowing in a direction that is approaching the danger zone, and a problem may be imminent.

When the wind direction is within the light grey 'warning' zone, the zone and outline of the wind vane change to yellow.
