NiMet strike: Why airports dey depend on meteorological agencies?
Flight delays and cancellations happen for Lagos, Abuja and Kano airports.
Workers from NiMet march for di street of Lagos, wit placards wey read: "No weather, no flight; fly at your own risk."
While one airline, United Nigeria Airlines, say dem bin dey find alternative sources for weather information, anoda airline, Air Peace, bin announce di suspension of all flight operations on Thursday.
Di strike now don dey called off for two weeks after Nigeria Minister of Aviation and Aerospace Development Festus Keyamo meet with NiMet unions on Thursday.
Dis na three key reasons why meteorology dey important to aviation:
Safety
While e dey safe to fly inside bad weather, meteorological agencies fit alert pilots to any significant weather hazards, like thunderstorms, icing or low visibility caused by low clouds or fog.
Turbulence for flight dey very common, however thunderstorms fit make am more serious, putting passengers safety at risk.
While turbulence dey highly unlikely to make plane crash, e dey known to cause severe injuries to passengers – and even death.
Aviation forecasts fit also identify areas of Clear Air Turbulence (CAT), wey be wen temperature change create different wind speeds and direction.
Pilots fit use dis weather information to den fly around areas of turbulence to minimise any danger or to cancel flight altogether.
For Nigeria, heavy rainfall and thunderstorms dey more common at certain times of di year – e make weather information all modire important.
"Any time you get widespread thunderstorm outbreak, e fit dey dangerous," George Delanjian, one aviation meteorologist based in US tok.
"Lightening fit strike di aircraft and serious turbulence fit happen. In most cases, meteorologists know wen and wia thunderstorms go happen."
Weather information dey also become more important for flight safety, sake of say some studies show say instances of serious turbulence dey increase, wey fit be due to climate change.
Efficiency
Information about di weather dey crucial for pilots wey dey prepare a flight plan. Di temperature, humidity, pressure and wind fit impact di ability to maintain a safe flying altitude and di ability to reach di destination with enough fuel.
Information about jet streams – wey be strong bands of winds – fit help di plane to arrive more quickly at im destination. Flight plan fit also include alternate airports wey di plane fit divert too if change in weather conditions happen.
"Meteorological agencies go provide information to airport as part of Meteorological Aerodrome Report [METAR] - wey be hourly reports wey show di current weather and Terminal Aerodrome Forecast [TAF] - wey give di forecast throughout di day," Simon King, BBC meteorologist tok.
"Any pilot absolutely suppose get am to plan dia flights. For example, if di weather for di airport wia plane dey due to land no dey favourable, pilots fit dey aware of oda airports to divert to - while making sure say enough fuel dey to do so."
So, weather reports no dey just about safety, dem dey also help airlines to save time, fuel and money.
Ground operations
Weather information dey just as important on di ground as e dey for di pilots in di sky. Meteorological agencies provide airports with information wey dey prepare dem for conditions wey fit affect di runway visibility and di ability to take off and land safely. In particular, pilots go dey look di forecasts for di speed and direction of di wind. Dis go affect di runway di pilot go use.
Weather information fit also help make decisions on de-icing procedures, di loading and unloading of aircraft and re-fuelling.
"If thunderstorm dey, planes no dey allowed to refuel in case of lightening," King add.

British and Irish Lions defeat Brumbies but issues remain as Australia Test series looms
Audition: Garry Ringrose celebrates with Jamison Gibson-Park after scoring the Lions' fourth try against the Brumbies in Canberra (Getty Images) The British and Irish Lions continued to warm up for their three-Test summer series against Australia with a 36-24 win over the ACT Brumbies in Canberra. Andy Farrell picked what many consider to be his likely Test team for Wednesday's clash with Australia's best-performing Super Rugby franchise at the GIO Stadium and received an overall mixed display, with Blair Kinghorn limping off early to present another key injury concern. Advertisement While the Lions took an obvious step forward in attack with five tries - and three more over the line not grounded - to follow a thoroughly scrappy 21-10 victory against the New South Wales Waratahs in Sydney on Saturday, they also made another sluggish start and conceded four tries, shipping double-digit penalties as their breakdown struggles continued and committing more frustrating handling errors. There were plenty of positives to take from a fourth consecutive win Down Under but also remain a number of issues to work on for Farrell's side 10 days out from the first Test against the Wallabies in Brisbane on July 19, with only one more warm-up fixture to come now - against a strong-looking AUNZ Invitational XV at the Adelaide Oval this weekend. Injury concern: Blair Kinghorn went off with an apparent knee issue after only 25 minutes in Canberra (Getty Images) The Lions looked to be caught cold again on a chilly winter's night in Canberra, conceding early penalties before the weakened Brumbies - missing a host of Australian internationals in Allan Alaalatoa, James Slipper, Nick Frost, Rob Valetini, Len Ikitau, Billy Pollard, Tom Wright and Noah Lolesio - capitalised on a ferocious start with just four minutes on the clock through number eight Tuaina Taii Tualima, whose opening try went unconverted. Advertisement The Lions' attack looked rather out of sync once more, until they took advantage of a needless spilled pass forward and hit back after quarter of an hour, England forward Ollie Chessum showing his handling skills as he was put through to level the score ahead of a botched conversion attempt by Finn Russell. The momentum continued to swing back and forth in a high-tempo affair and the Lions thought they had gone ahead when James Lowe finished in the left corner, but the try was not given on the field and there was nothing conclusive on the TMO replays to overturn that decision. The Lions then lost Kinghorn - the front-runner to be their Test starter at full-back - to what looked like a knee injury that he initially tried to play through, failing to hide his frustration as he limped off the pitch, replaced by Marcus Smith. Advertisement Ireland wing Lowe would not be denied and finished off a wonderful passing move as the Lions' attack finally clicked in devastating fashion, the ever-influential Russell destined not to miss again from the tee for the rest of the night. The two sides traded further tries late in the first half to make it 19-10 to the Lions, Smith breaking through with the clock in the red after prolific wing Corey Toole had punished some narrow defending for the Brumbies. The Lions had their fourth try seven minutes after the interval, Garry Ringrose collecting Smith's clever kick through to score and give the tourists some breathing space. Advertisement Taking his chance: Marcus Smith registered the Lions' third try of the night on the stroke of half-time (Getty Images) You sensed that the Lions would likely start to pull away, just as they did in huge wins over the Western Force and Queensland Reds to kick off the tour, but, like the Waratahs before them, the Brumbies showed impressive resolve and answered shortly afterwards through centre Hudson Creighton to make it 26-17. The Brumbies' competitiveness in their quest to follow up a famous win from 2013 was shown by the Lions opting to kick a penalty through Russell to extend their lead on the hour mark. Advertisement A trademark burst from the fit-again Henry Pollock had the Lions back deep in the 22 and the home defence could not hold out as Josh van der Flier, whose earlier effort was not given with no clear evidence of grounding, finished off a ruthless rolling maul with just over 10 minutes to go. But the Lions still could not shut the door in defence as replacement hooker Liam Bowron scored from close range to bring the Brumbies back within 12, Chessum then denied his second try at the death after the ball was ruled as being held up after review.

A Trump tariff letter is the best news this Southeast Asian junta has had in a while
For most world leaders, tariff letters from US President Donald Trump mean a big headache. But for one Southeast Asian general, the communique is being spun as welcome recognition of the embattled, isolated and reviled junta he leads. Senior General Min Aung Hlaing, head of the military that seized power in Myanmar in 2021 after ousting a democratically elected government, said it was he who had the 'honor' of receiving of Trump's letter sent on Monday announcing new tariffs, state media Global New Light of Myanmar reported on Friday. The letter, which stated the United States would be imposing a new tariff rate of 40 percent on Myanmar's exports to the US starting August 1, was received with 'sincere appreciation,' the newspaper said. The United States and most Western countries have not recognized the junta as the legitimate government of Myanmar, also known as Burma. The military's power grab sparked a catastrophic civil war now in its fifth year, with pro-democracy fighters and ethnic rebel groups battling the military across swaths of the country. The United Nations and other rights groups have accused the military of war crimes as it battles to cling to power. The US, the United Kingdom and the European Union have all sanctioned the military and sought to limit contact with its representatives on the world stage. Washington and most Western capitals no longer station fully accredited ambassadors in Myanmar, a diplomatic snub the ruling generals have long chafed at. But this week's letter was spun as an 'encouraging invitation to continue participating in the extraordinary Economy of the United States,' Min Aung Hlaing was quoted as saying, adding a high-level negotiation team could be sent 'as quickly as possible to the US to discuss with the relevant authorities,' if needed. CNN has reached out to the US embassy in Myanmar for details on how the letter was delivered and for comment on whether it signals a change in Washington's stance on the junta. Min Aung Hlaing also asked that Washington consider lifting and easing economic sanctions on Myanmar, 'as they hinder the shared interests and prosperity of both countries and their peoples,' he was quoted as saying. The general – who led Myanmar's military in 2017, when the United States said it committed genocide against the Rohingya minority – also took the chance to heap praise on Trump. He hailed his 'strong leadership in guiding his country towards national prosperity with the spirit of a true patriot, as well as continued efforts to promote peace on the global stage,' the Global New Light said. Min Aung Hlaing also thanked Trump for 'regulating broadcasting agencies and funds, which have sometimes exacerbated the existing conflicts' – an apparent reference to the Trump administration's funding cuts to US outlets such as Radio Free Asia and Voice of America. Both outlets have long been popular across Myanmar for their independent reporting, and have become even more vital following the junta's crackdown on the free press. Min Aung Hlaing sought to appeal to a longstanding Trump grievance – his long-debunked claims of massive election fraud in the 2020 election won by former President Joe Biden. 'Similar to the challenges the President encountered during the 2020 election of the United States, Myanmar also experienced major electoral fraud and significant irregularities,' he was quoted as saying. The election he was referring to in Myanmar was won resoundingly by Nobel laureate Aung San Suu Kyi and her National League for Democracy party, which won a second term at the expense of the military's proxy party. International observers at the time concluded the election was largely free and fair but the military soon began making unsubstantiated claims of massive fraud. Weeks later, it launched its coup, ending a 10-year experiment with democracy and plunging Myanmar into turmoil. Suu Kyi has been in military custody since, and is serving a 27-year jail sentence following a closed-door trial that critics say was a sham and designed to remove the popular leader and longtime foe of the military from political life.
