Tornado debris can travel surprisingly far after a violent storm
Intense tornadoes are capable of producing destructive winds of more than 300 km/h. These whirlwinds can reduce the mightiest oak tree to splinters and entirely demolish a solidly built home. All that debris doesn't stick around where it came apart. A tornado can loft debris hundreds of kilometres away from where it originated—and some of that debris is incredibly heavy. DON'T MISS: Tornadoes suck upward like a vacuum Tornadic winds are capable of producing tremendous damage on their own. But these storms are unique in that they suck upward rather than just blowing wind around in a circle. This upward component of the violent winds provide tornadoes the leverage they need to peel roofs from homes, uproot trees, and toss vehicles as if they were toys. Winds within a twister extend from the surface deep into the heart of its parent thunderstorm. While most debris falls back to the ground in a hurry, some objects can loft high into the thunderstorm—and then take a long ride on upper-level winds. It's common after a violent tornado to see debris travel dozens, if not hundreds, of kilometres downwind from the point of damage. This is called debris fallout—and it's actually possible to see it on weather radar. The radar image above shows the debris fallout from a violent tornado in southern Mississippi on April 12, 2020. A powerful EF-4 tornado damaged or destroyed thousands of structures along its 110-kilometre path. Special technology embedded in weather radar allows us to 'see' debris suspended in the atmosphere during and after a tornado. The tornado itself is visible as a tight ball of debris. Strong upper-level winds blew a tremendous amount of debris downwind, which the radar was easily able to detect. It takes tremendous forces to loft heavy debris like metal and wood long distances. A strong EF-2 tornado in April 2018 struck Greensboro, North Carolina, and tossed heavy pieces of corrugated metal nearly 30 kilometres downwind. Lighter objects like envelopes and photographs are known to travel hundreds of kilometres. One paper published in 1998 found that pieces of paper had been transported up to 335 km downwind from a tornado. Another study in 1995 found that a twister in Barneveld, Wisconsin, had transported 'traceable' pieces of paper—such as invoices and personal cheques—177 km away from the damaged town.

Honeywell raises 2025 forecasts on sustained demand for aerospace parts, services

(AP Photo/Alan Diaz) Honeywell raised its annual forecasts after beating Wall Street expectations for second-quarter results on Thursday, buoyed by strong demand for its aerospace parts and maintenance services. Shares of the company rose 1.5 per cent in premarket trading. The company, which supplies avionics and flight control systems to Boeing and Airbus, has benefited from rising demand as planemakers ramp production after long delays due to supply chain issues. Honeywell has also capitalized on a shortage of new jets, providing aircraft maintenance and repair services as airlines continue to fly an older, cost-intensive fleet. The company's aerospace division, its biggest revenue generator, posted a 10.7 per cent jump in sales to US$4.31 billion in the second quarter. Honeywell now sees 2025 adjusted profit per share between US$10.45 and $10.65, up from its previous forecast of US$10.20 to US$10.50. The company also raised its revenue outlook and now expects between US$40.8 billion and US$41.3 billion for the year, up from the US$39.6 billion and US$40.5 billion it had previously forecast. The engines-to-switches conglomerate has been in the process of streamlining its portfolio under CEO Vimal Kapur, making acquisitions as well as shedding assets weighing on its business. After pressure from activist investor Elliott Management, Honeywell in February announced plans to separate its businesses. The company will spin off its aerospace business and retain the automation segment, which will be led by Kapur. Honeywell is reviewing alternatives for its productivity solutions and services unit and the warehouse and workflow solutions division, which have been a drag on the company's earnings in the past few quarters. The industrial automation unit, which houses the businesses, reported a five per cent fall in sales in the second quarter. Total sales, meanwhile, rose 8.1 per cent to US$10.35 billion, exceeding analysts' average estimate of US$10.07 billion, per data compiled by LSEG. Honeywell reported an adjusted profit of US$2.75 per share, also beating analysts' expectations of US$2.66. --- Reporting by Utkarsh Shetti in Bengaluru; Editing by Shinjini Ganguli

Nelson-Tasman region to get its own rain radar by 2027

The region, which has endured repeated floods caused by heavy rain in recent weeks, as well as five states of emergency in the past 14 years, does not have its own rain radar . Associate Transport Minister James Meager said the existing contract with MetService was being amended to immediately begin the procurement of a new radar for the region. MetService was aiming to purchase it by next Autumn and get it operational that summer, in late 2026 or early 2027. A new radar will cost up to $5 million, with operating costs of around $800,000 a year. Immediate work will begin using existing MetService funding. The radar would help better prepare the community for future disasters, Meager said. "This is something the community has asked for, and it's my hope the investment will give locals peace of mind over their individual and property safety in future events. "Weather radars play an incredibly important role in emergency management once an event starts. They allow forecasters to monitor the progression of a storm, refine short-term forecasts and warnings, and provide specific guidance to emergency managers about the distribution and intensity of rainfall." Emergency Management and Recovery Minister Mark Mitchell said Nelson-Tasman had experienced several high-impact flooding events in recent years. "Since 2011, there have been five states of emergency declared in the region. Providing Nelson-Tasman with a new weather radar will give emergency managers greater ability to monitor rainfall and flooding risk during a severe weather event, reducing the risk of loss of life and property. "In addition to the new weather radar, the government has committed to strengthening the emergency management system to ensure it is fit for purpose to manage significant, widespread emergencies. "Investments in modern technology and trained personnel, along with clear governance structures and assurance, will ensure faster, more effective emergency management."
