Paragliding Thermaling⁚ A Guide

Thermaling is a technique used by paragliders to gain altitude by utilizing rising columns of warm air. These thermals are created when the sun heats the ground unevenly, causing pockets of air to rise. Paragliders can identify thermals by looking for signs such as circling birds, dust devils, or changes in wind direction.

What is Thermaling?

Thermaling is a technique used by paragliders to gain altitude by utilizing rising columns of warm air. These thermals are created when the sun heats the ground unevenly, causing pockets of air to rise. Paragliders can identify thermals by looking for signs such as circling birds, dust devils, or changes in wind direction.

When a paraglider enters a thermal, they will experience an increase in lift, which allows them to climb higher. Paragliders can stay in a thermal for extended periods of time, gaining significant altitude. Thermaling is an essential skill for cross-country paragliding, as it allows pilots to extend their flights and cover greater distances.

There are two main types of thermals⁚ bubble thermals and ridge thermals. Bubble thermals are isolated columns of rising air, while ridge thermals are formed along the slopes of hills or mountains. Paragliders typically use different techniques to enter and maintain their position in each type of thermal.

Thermaling can be a challenging but rewarding technique. With practice, paragliders can learn to identify thermals and use them to gain altitude and extend their flights.

How to Find Thermals

Finding thermals is a key skill for paragliding pilots. Thermals are columns of rising air that can help paragliders gain altitude and extend their flights. There are a number of ways to identify thermals, including⁚

• Circling birds⁚ Birds often circle over thermals, as they use the rising air to gain altitude. Paragliders can look for circling birds to help them locate thermals.
• Dust devils⁚ Dust devils are small, rotating columns of air that can be seen rising from the ground. Dust devils are often associated with thermals, as they are caused by the same rising air currents.
• Changes in wind direction⁚ Thermals can cause changes in wind direction. Paragliders can use their variometer to detect changes in wind direction, which can help them locate thermals.
• Clouds⁚ Thermals can sometimes be identified by the presence of clouds. Cumulus clouds, in particular, are often associated with thermals. Paragliders can look for cumulus clouds to help them locate thermals.

Once a paraglider has identified a thermal, they can use a variety of techniques to enter and maintain their position in the thermal. These techniques will be discussed in the next section.

It is important to note that thermals can be difficult to find, especially in weak or unstable conditions. Paragliders should be patient and persistent when searching for thermals. With practice, paragliders will become more skilled at identifying and using thermals to gain altitude and extend their flights.

Tips for Finding Thermals

• Fly at the right time of day. Thermals are typically strongest during the middle of the day, when the sun is at its highest.
• Fly in the right location. Thermals are more likely to be found over land than over water. They are also more likely to be found in areas with uneven terrain, such as hills and mountains.
• Use your variometer. A variometer is an instrument that measures the rate of climb or descent. Paragliders can use their variometer to help them locate thermals.
• Be patient and persistent. Finding thermals can take time and practice. Paragliders should be patient and persistent when searching for thermals.

Entering a Thermal

Once a paraglider has identified a thermal, they can use a variety of techniques to enter the thermal. The most common technique is to fly into the thermal from the upwind side. This will help the paraglider to gain altitude quickly and efficiently.

To enter a thermal from the upwind side, the paraglider should⁚

• Identify the upwind side of the thermal. This can be done by looking for the direction of the wind and the movement of the circling birds or dust devils.
• Fly towards the upwind side of the thermal.
• Once the paraglider is close to the thermal, they should turn into the thermal and start to climb.

The paraglider should try to fly in the center of the thermal, where the rising air is strongest. The paraglider can use their variometer to help them stay in the center of the thermal.

Once the paraglider has entered the thermal, they can begin to climb. The paraglider should climb at a rate that is comfortable for them. It is important to avoid climbing too quickly, as this can cause the paraglider to overshoot the thermal.

The paraglider should continue to climb until they reach the top of the thermal. The top of the thermal is typically marked by a decrease in the rate of climb. Once the paraglider reaches the top of the thermal, they can begin to glide away.

Tips for Entering a Thermal

• Be patient. It may take some time to find the center of the thermal.
• Use your variometer. A variometer can help you stay in the center of the thermal.
• Don’t climb too quickly. Climbing too quickly can cause you to overshoot the thermal.
• Be aware of other paragliders. Make sure to give other paragliders plenty of space when entering a thermal.

Maintaining Your Position in a Thermal

Once a paraglider has entered a thermal, they need to be able to maintain their position in the thermal in order to continue climbing. There are a few key techniques that paragliders can use to maintain their position in a thermal⁚

• Fly in the center of the thermal. The center of the thermal is where the rising air is strongest. Paragliders should try to fly in the center of the thermal as much as possible.
• Use your variometer. A variometer can help paragliders stay in the center of the thermal. Paragliders should use their variometer to monitor their rate of climb and make adjustments as needed.
• Bank into the thermal. Banking into the thermal will help paragliders to stay in the center of the thermal. Paragliders should bank into the thermal gradually, using small, smooth movements.
• Be aware of other paragliders. Paragliders should be aware of other paragliders when flying in a thermal. Paragliders should give other paragliders plenty of space and avoid flying too close to them.

Paragliders should also be aware of the following factors when trying to maintain their position in a thermal⁚

• Wind speed. The wind speed can affect the strength and size of a thermal. Paragliders should be aware of the wind speed and make adjustments as needed.
• Terrain. The terrain can also affect the strength and size of a thermal. Paragliders should be aware of the terrain and make adjustments as needed.
• Time of day. The time of day can also affect the strength and size of a thermal. Paragliders should be aware of the time of day and make adjustments as needed.

By following these tips, paragliders can increase their chances of maintaining their position in a thermal and continuing to climb.
