Turbulence is getting worse around the world because of #climatechange with the trend expected to continue - Turbulence refers to atmospheric instability, such as sudden, unpredictable air movements - There are 2 common types of turbulence: 1. #storms - which cause major changes in wind strength and air flow, and thunderstorms in particular can endanger aircraft. But these show up on weather radars, and can be avoided in flight. 2. "Clear air turbulence" - which is invisible and therefore seen as more dangerous. It does not show up on cockpit instruments and the only warnings are from aircraft that have already been through it. - The warming of the planet, and record sea temperatures as they absorb heat, are increasing the intensity of #tropicalstorms - Meanwhile, severe "clear air turbulence" in the north #atlantic, one of the world’s busiest flight paths, has increased 55% since 1979, with this type of turbulence expected to double or even triple in some parts of the atmosphere in the coming decades "There is a clear . . . relationship. The more #co2 you put into the atmosphere, the more you fill it with heat and the more turbulence there is." https://lnkd.in/ejRwvZyN #climatecrisis

🌍✈️ Navigating the Skies: Europe’s Aviation Faces Turbulent Weather Ahead Over the coming days, Europe’s aviation sector is gearing up for a tough battle with nature. Warm air advection and a diffluent jet stream exit are creating high turbulence kinetic energy (TKE) across Western and Central Europe. The result? Widespread Turbulence SIGMET warnings and Pilot Reports, even at cruising altitudes. But that’s not all. Frontal zones are sweeping in, bringing icing risks at lower and mid-levels, while intensifying jet streams over the Alps are expected to generate clear-air turbulence (CAT) from mountain waves. From takeoff to cruising, it’s a bumpy ride in the making. Here’s the good news: Advanced weather intelligence, powered by high-resolution models like #EURO1k, is making a real difference. These tools provide pinpoint forecasts for turbulence and icing, enabling aviation professionals to plan smarter, mitigate risks, and maintain safety standards—ensuring operations stay as smooth as possible even in the most challenging conditions. 👉 How do you tackle weather challenges in your operations? Let’s discuss how cutting-edge weather models can support your aviation strategies.

Great to see BBC News reporting on our 2030 Sustainable Aviation Goals report. Goal 1 - Operation Blue Skies - calls on aviation leaders to establish ‘Living Labs’ by the end of 2025 to address uncertainties in #contrail avoidance, which could reduce the #climate impact of #aviation by up to 40%. Contrails act as a blanket 🛏 in our skies, typically covering around 1/1,000th of the Earth's 🌍 surface at any one time. Whilst each contrail only last hours ⌛ , they're constantly replaced by the exhausts of aircraft flying in sky. Whilst there's significant uncertainty (+/-70%), the rate at which the contrail blanket warms the planet (the Effective Radiative Forcing) is estimated to be 57 mW/m2 - that's the same warming rate as 32 billion tonnes of CO2 in the atmosphere ♨ (for context, roughly 12 months of emissions from all sectors combined). It's crucial that we urgently act to create Airspace-Scale Living Labs to have the capability to test, learn, and pivot whilst operating within a realistic airspace environment. 🔬 ✈ #NetZero #SustainableAviation #NonCO2 Whittle Laboratory Cambridge Institute for Sustainability Leadership (CISL) https://lnkd.in/e9XJSCzN

You're absolutely right. This approach demonstrates a significant shift in aviation weather management, emphasizing proactive strategies over reactive ones. Here's a breakdown of the key points: Innovation: DTN is leveraging cutting-edge technology to enhance aviation weather forecasting and monitoring. Collaboration: The integration of 24/7 Aviation Meteorologists with advanced data sets creates a powerful synergy between human expertise and technological capabilities. Proactive Operations: This combination allows airlines and airports to anticipate and prepare for weather-related challenges rather than simply responding to them as they occur. Continuous Monitoring: The 24/7 availability of meteorologists ensures round-the-clock vigilance and support for aviation operations. Enhanced Data Sets: Upgraded and updated weather data provides more accurate and timely information, crucial for making informed decisions in aviation. Operational Efficiency: By shifting from reactive to proactive strategies, airlines and airports can potentially reduce delays, improve safety, and optimize resource allocation. Risk Mitigation: Better weather prediction and preparation can lead to improved risk management in aviation operations. This approach not only demonstrates DTN's commitment to innovation but also highlights the potential for significant improvements in aviation safety, efficiency, and customer satisfaction. It's a prime example of how technological advancements and human expertise can work together to drive progress in the aviation industry.

As calls for action increase over the climate impacts of aircraft contrails, airborne research is intensifying with the expansion of two key projects in Europe and the US, reports Tony Harrington for GreenAir News. In Germany, Lufthansa has started converting an Airbus A350-900 for use as a flying research laboratory as part of IAGOS-CARIBIC, a long-running European programme that uses commercial airliners to gather data on air quality for scientific evaluation. The A350 will be equipped with around 20 measuring instruments for a multi-year project beginning late next year to measure trace gases, aerosol and cloud parameters on selected long-haul flights. In the US, engine manufacturer GE Aerospace and NASA - National Aeronautics and Space Administration have just completed two flights with a Boeing 747 testbed aircraft to record three-dimensional imaging of contrails to better understand how they form and behave in certain conditions. The 747’s emissions were scanned using Light Detection and Ranging (LiDAR) technology installed on a following aircraft. #sustainableaviation #AviationNonCO2 #contrails #aviationresearch Mark Pilling Grazia Vittadini Arjan Hegeman Chelsey Levingston, APR Joachim Majholm German Aerospace Center (DLR) SATAVIA Adam Durant Conor Farrington Klaas Pel Claudia Huegel Royal Aeronautical Society Ian Poll Read the full article here: https://lnkd.in/eRwTaqiT

Climate change appears to be sending a strong "sell" - or at least shorting - signal for airline stocks - and #jetfuel for that matter. "Severe clear-air turbulence in the north Atlantic, one of the world’s busiest flight paths, has increased 55 per cent since 1979, according to Paul Williams, a professor of atmospheric science at the University of Reading. His forecasts show that this type of turbulence, which does not show up on weather radars and can hit without warning, will double or even triple in some parts of the atmosphere in the coming decades." #airlines #climatechange

You rarely hear about them, but jet streams are an atmospheric phenomenon that significantly affects aspects as important as the climate or, within the aeronautical field, the duration and stability of certain flights and even the economy of some airline companies. Jet Streams are huge flows of air that move through the atmosphere at high speed and significantly affect the climate and, specifically, air navigation. They are an essential part of some aspects of our lives, especially our interaction with the atmosphere, although the vast majority of the population still does not really know of their existence. https://hubs.la/Q02Hz-H_0
