Picture yourself soaring through the clouds, floating above picturesque landscapes, and experiencing a thrilling adventure like no other. Sounds fun, right? Hot air balloon rides have captivated the imaginations of people around the world for centuries, offering a unique and awe-inspiring way to view the beautiful mountains and landscapes from above.
Let’s delve into the intricacies of balloon flight and learn about the ideal weather condition that makes every moment magical. Whether you’re a passionate adventurer or a curious traveller attending the renowned balloon festival in Northam, Australia, this blog will help you uncover the secrets behind the best ballooning weather.
Hot air balloons can fly in both warm and cold weather conditions, but the ride is more stable if the air is colder. In hot weather, one must pay attention to the thermal activity.
The ideal time to fly a hot air balloon is when the air temperature is slightly cooler, such as early morning or late evening.
The colder the atmospheric temperature, the easier and faster it is to create a difference in temperature between the air inside the envelope and the ambient air temperature. Cool days make the balloon buoyant easier. We need to understand that hot air balloons fly because the air inside the balloon, by being hot, is less dense that the equivalent volume of air outside of the balloon displaced by the envelope itself.
Less dense matter will float over denser matter. Put another way, there are less MOLECULES of air inside the balloon when it is hot compared to it being full of air at atmospheric temperature.
Let’s explain this in a different way. At standard temperature and at sea level, air weighs 1.222 kg per cubic metre. A medium sized commercial balloon can have, for example, 8000 cubic metres of air inside it…this means the air inside a balloon this size weighs almost 10 tons!!!
By heating the air inside a balloon and making the balloon less dense (having less molecules of air inside it), the weight of this air inside will weigh less, for example 2.5 tons less if you heat up the air inside the envelope to close to 100 degrees Celsius. This means that the balloon would rise unless we hold it down with a tether. See what we are saying here? If we attach a basket to the balloon and the basket and balloon (and passengers plus all the equipment, tanks and burners) weighs less than 2.5 tons it would float.
This buoyancy is what a balloon pilot controls by the use of the burners. Allow the air to cool down a little, it will start to descend; heat it up a little, it will ascend. A balloon pilot controls the air inside the balloon to make it float, rise and descend into the air currents available to him to navigate the winds to a suitable landing location.
Flying a hot air balloon in warm weather is possible if certain measures are considered. The first thing to remember is that the air inside the balloon must be warmer than the air temperature outside to keep afloat.
This means more fuel and more heat will be needed to heat the air inside the balloon. The fabric will have a maximum temperature allowed by the manufacturer, so a balloon pilot is not meant to surpass this. To keep it simple, contrary to what many people believe, hot air balloons prefer cool weather, definitely!!
Is it possible to enjoy a ballooning experience if it starts raining during the ride? Well, balloon rides can still take place in rainy conditions, if the weather is not excessively severe. However, it’s important to note that flying in even light rain can be hazardous if proper safety measures are not followed.
The moisture in the air and on the envelope weighs down the balloon, making it heavier and more difficult to control. Hence, it is important to be careful when ballooning in rainy conditions and most pilots will cancel a flight if they know rain is on its way.
Flying a hot air balloon in cloudy weather is subject to the type of clouds. Certain clouds, like high convective clouds, pose risks that balloon pilots will avoid. Examples of such clouds include cumulonimbus and towering cumulus clouds.
It is important to note that flying a hot air balloon in these conditions can be extremely dangerous, posing a threat to both the passengers and the balloon itself. This risk is further amplified when flying over bodies of water or challenging terrains, as finding a safe landing spot becomes more challenging.
