On the other hand, especially in Winter with dry air, the Soaring-index can be very high, even though conditions are very poor. This graph shows an atmospheric profile over time and is the most important diagram to estimate soaring conditions. It provides an overview of the thermodynamic stability and clouds. The bottom of the diagram corresponds to the forecast model ground level, which might differ significantly from the actual location height in complex terrain.
All color scales are fixed to compare forecasts at different locations and times. This diagram can get very crowded with information and thus become very hard to read, but that is a good thing because as a rule of thumb: "The harder to read, the worse the soaring! This is an example of excellent soaring conditions as they occur frequently in Bitterwasser Namibia , one of the best soaring spots in the world.
Such conditions will never occur in most places, but you can find similar patterns reaching lower altitudes on good days almost everywhere.
Upper air wind conditions for the next days are displayed here. Strong wind shears are dangerous and should be avoided. Already weak wind shears disrupt thermals. The color scales are also fixed. Mes lieux. Recherche de lieu. It is separated into 4 parts: Surface conditions All diagrams show hourly data for Marbella for 3 days.
Stability indices Stability indices should not be understood as a summary of thermal conditions. Soaring conditions daily summary ThrHGT : For each day the maximum heights of dry thermals as well as the maximum expected soaring height for a glider plane is given. Heights are in meters above ground level not above sea level.
A value of 0m indicates that dry thermals do not support a glider plane. Furthermore, the thermal index TI for , , and hPa mb is forecast.
The more negative the thermal index, the stronger the expected thermals: Thermal-Index Expected thermals or -8 Very good lift and a long soaring day. Thermals are strong enough to hold together even on a windy day. Remember that the TI is a forecast value. A miss in the forecast maximum or a change in temperature aloft can alter the picture considerably. Uplift caused by wind is not considered Mountain waves, convergence etc. Minimum 1. Soaring-Index: A measure of stability considering temperature and humidity between and hPa.
Be aware the Soaring-Index values can change significantly during summer over short periods of time due to temperature and moisture advection. In the winter, when temperatures are very cold, the moisture terms are very small. So, even the Soaring-Index is fairly large, it does not mean that conditions are favorable for thunderstorms because of the lack of moisture.
The index gives no reliable data if the depth of the convection layer ends below hpa. Be aware that strongly negative values indicate excellent soaring conditions, but severe thunderstorms are likely and could be very dangerous.
