Previous-afternoon sunshine affects how strongly the land and mountain slopes heated up and the conditions in which the overnight circulation begins.

The temperature contrast between Verona and Innsbruck represents the different rates of heating in the Po Valley and Alpine region, and therefore the thermal drive.

Overnight wind at 100 metres shows whether the broad flow supports Peler, overrides it or mixes the lower atmosphere.

Cloud slows overnight cooling. A clear night supports the temperature and pressure differences from which Peler develops.

Evening or overnight rain affects cooling, changes the air mass and often disrupts Peler’s development.

Overnight humidity describes the air mass and indicates whether cloud or fog may form and alter Peler’s development.

Morning cloud reduces solar radiation and therefore the energy available for Ora’s thermal development.

The south–north wind component shows whether the broad flow is aligned with Ora or works against it.

The expected maximum temperature in Torbole represents the amount of daytime heating and the thermal energy available.

Rain and showers limit heating and can interrupt the local circulation. Daytime precipitation therefore usually works against Ora.

High humidity often accompanies weaker heating, haze or cloud. In drier air, the thermal circulation can usually develop more freely.

The temperature contrast between Verona and Innsbruck represents the different rates of heating in the Po Valley and Alpine region, and therefore the thermal drive.

The west–east component of the wind at 100 metres lets the model assess the direction of the broad flow separately from its overall speed.

Wind at 100 metres represents the broad flow over the lake. Depending on its direction, it can support or override the local wind system.

This value shows how the Innsbruck−Verona pressure gradient changes from early morning to midday.

Evening or overnight rain affects cooling, changes the air mass and often disrupts Peler’s development.

The Innsbruck−Verona gradient describes the broad pressure distribution between the Alps and Po Valley. A very strong northerly gradient can suppress Ora; a favourable distribution lets it develop more freely.

Morning cloud reduces solar radiation and therefore the energy available for Ora’s thermal development.

The pressure gradient between Bolzano and Verona represents the pressure distribution between the Alps and Po Valley. This affects the thermal draw through the Sarca Valley.

The expected maximum temperature in Torbole represents the amount of daytime heating and the thermal energy available.

Evening or overnight rain affects cooling, changes the air mass and often disrupts Peler’s development.

The overnight Bolzano−Verona pressure difference is the strongest pressure driver in the Peler model: it indicates whether air is being pushed south along the lake.

Overnight humidity describes the air mass and indicates whether cloud or fog may form and alter Peler’s development.
