Bushfires in Australia in 2019-2020
The 2019-2020 Australian bushfire season, also known as Black Summer, was one of the most intense and catastrophic fire seasons in the country's history. The fires, which began in June 2019, were exacerbated by exceptionally dry conditions, a lack of soil moisture, and early fires in Central Queensland. The most severe blazes peaked between December 2019 and January 2020 and affected mainly the southeast of Australia.
During this period, hundreds of fires ravaged Australia, burning an estimated 24.3 million hectares of land, destroying over 3,000 homes and thousands of other buildings, and causing economic losses estimated between A$100 and A$230 billion. The human toll was also devastating, with at least 34 lives lost directly to the fires and more than 400 deaths attributed to bushfire smoke, according to the Medical Journal of Australia. The impact on wildlife was equally devastating, with estimates suggesting over a billion animals perished, including a third of the koala population.
The bushfires also disrupted air travel in Australia, which is heavily reliant on aviation due to the vast distances between towns and cities. While planes mostly continued operating, Qantas cancelled all services to and from Canberra on January 5, 2020, due to adverse weather caused by the fires. Another Qantas flight from Melbourne to Canberra encountered a pyrocumulus cloud, causing the sky to turn black and creating turbulence. These clouds are a result of extreme surface heat from wildfires and behave similarly to regular storm clouds, demonstrating how fires can create their own weather systems.
The smoke haze from the fires lowered visibility, particularly at smaller airports without Instrument Landing Systems (ILS), and could enter aircraft cabins, alarming passengers. The strong smell of smoke and potential turbulence associated with the fires further complicated flights. While there is no specific mention of Brisbane Airport being affected by these issues, the widespread nature of the bushfires and their impact on aviation suggests that it may have experienced similar challenges.
The bushfires' scale and intensity prompted predictions that such events could become more common due to climate change. The formation of a National Bushfire Recovery Agency and the government's pledge of A$2 billion for recovery efforts underscored the magnitude of the disaster. The recovery and rebuilding process is ongoing, focusing on community resilience, wildlife rehabilitation, and volunteer firefighter support.

Smoke haze and visibility issues
While I could not find specific information on Brisbane Airport being affected by fires, there is some information on the impact of Australia's bushfires on airport visibility.
Smoke haze from fires can reduce visibility for aircraft, similar to how fog would affect visibility. This is a significant challenge for the aviation industry, especially at smaller airports without ILS landing aids. In some cases, the presence of nearby fires may lead to the closure of an airport or the grounding of all flights to ensure safety.
The smoke haze can also enter the cabin, potentially alarming passengers. Additionally, there may be turbulence associated with the fires, and the strong smell of smoke can be off-putting.
While modern airplanes have complex guidance systems to aid in landing or taking off in inclement weather, fires pose a unique set of challenges. Saj Ahmad, StrategicAero Research chief analyst, notes that "any fires in the vicinity of an airport would almost certainly mean the airport closes or all flights remain grounded."
Furthermore, the ash and smoke from bushfires can potentially affect aircraft engines. While it is known that volcanic ash contains coarse particulates that can damage aircraft engines, the exact effects of bushfire ash and smoke are not fully understood.
To ensure safe operations, NOTAMs (Notice to Airmen) should provide pilots with information on fire location, spread, and the height of smoke. This information is critical for pilots to make informed decisions and take necessary actions to ensure the safety of their aircraft and passengers.

Pyrocumulus clouds and weather systems
Pyrocumulus clouds, also known as flammagenitus, are dense cumuliform clouds associated with fire or volcanic eruptions. They are formed by a rising column of hot air and smoke coming off fires. The hot air cools once it reaches colder air in the upper levels of the atmosphere, and if there is a lot of moisture in the air, it leads to the formation of clouds. These clouds can sometimes produce rain to help extinguish a fire, although the rain often evaporates before reaching the ground due to the hot, dry environment. Pyrocumulus clouds can also cause a sudden increase in wind speed, which can dramatically worsen the wildfire that created the cloud.
When pyrocumulus clouds continue to grow, they can develop into pyrocumulonimbus clouds, which are capable of producing thunderstorms and lightning. Pyrocumulonimbus clouds can reach heights of 50,000 feet and generate their own weather systems of thunderstorms. The lightning generated by these clouds can even ignite additional fires. Pyrocumulonimbus clouds were observed during the Australian bushfires in late 2019 and early 2020, and more recently in Siberia during the Arctic heatwave.
The formation of pyrocumulus clouds is similar to that of cumulus clouds, which occur due to rising air caused by the ground being warmer than the air. Cumulus clouds form when moisture condenses around particulates that are usually dust. Pyrocumulus clouds, on the other hand, use smoke particles from the fire as condensation nuclei. These clouds are typically gray, black, or brown due to the presence of smoke and ash.
Pyrocumulus clouds are considered rare, especially in certain regions like the Northern Territory of Australia, making them a fascinating phenomenon for weather watchers. They are often associated with wildfires, but can also form during volcanic eruptions. In summary, pyrocumulus clouds are a result of intense heat from fires or volcanic activity, and they have the potential to develop into pyrocumulonimbus clouds, creating their own weather systems and impacting their surrounding environment.

Brisbane Airport fire evacuation
On 2 February 2019, Brisbane International Airport was evacuated as police responded to an 'emergency situation'. A man was seen chasing women in the departures terminal with a knife, triggering an emergency evacuation of the airport, the grounding of planes, and suspension of trains. Queensland Police and Australian Federal Police were on the scene and negotiated with the man, who they believed was involved in a domestic violence-related situation. The lockdown ended at 11 pm Brisbane time.
In addition to the safety risks posed by the incident, there was also concern about the impact on airport operations and passenger safety. During the evacuation, smoke alarms went off in the Qantas domestic area of the airport due to smoke coming from a cooking appliance, causing further delays for passengers.
While this particular incident at Brisbane Airport was not related to fires, Australia has experienced significant bushfires that have impacted airport operations in other parts of the country. In early 2020, fires ravaged large portions of the country, affecting visibility and creating unpredictable weather conditions. Qantas, for example, cancelled all services into and out of Canberra due to adverse weather caused by the blazes.
The impact of fires on airports underscores the challenges posed by such events to the aviation industry, particularly regarding visibility, weather conditions, and passenger safety.

Bushfire impact on aircraft and airports
While I could not find specific information on whether Brisbane Airport was affected by fires, here is some general information on the impact of bushfires on aircraft and airports.
Bushfires can have a significant impact on aircraft and airport operations, and while bushfires are not uncommon in Australia, the sheer scale of the blazes that ravaged the country in late 2019 and early 2020 took many by surprise. These fires presented several challenges for the aviation industry, with one of the biggest being visibility. Heavy fires can lead to smoke and haze, which lowers visibility, particularly at smaller airports without ILS landing aids. This can make landing and taking off more difficult and increase the risk of accidents. In some cases, airports may have to close or ground all flights if there are fires in the vicinity.
Smoke from bushfires can also enter aircraft cabins, causing alarm among passengers and potentially affecting their health. The strong smell and haze can be unsettling for passengers, and the smoke may contain harmful gases and particulates that can impact the health of passengers and crew, especially those with respiratory issues.
Additionally, fires can create their own weather systems, including pyrocumulus clouds, which can cause turbulence and other weather phenomena such as thunderstorms, hail, and lightning. These weather conditions can further complicate aircraft operations and affect flight paths.
To ensure the safety of aircraft and passengers, it is crucial to provide pilots with detailed information about the location, spread, and height of smoke from bushfires. This information can help pilots navigate safely and avoid areas with low visibility or severe weather conditions. While modern aircraft are equipped with complex guidance systems to assist in adverse weather conditions, the unpredictable nature of fires and the potential for rapid changes in conditions pose significant challenges.
The impact of bushfires on aircraft and airports highlights the critical role of technology in ensuring safe and efficient operations during such events. It also underscores the need for further research and the development of new technologies to address the unique challenges posed by large-scale bushfires.
