A deadly storm's path of destruction: Could data gaps be to blame?
The recent powerful storm that wreaked havoc on western Alaska's small communities may have been even more devastating due to a critical data gap. The lack of weather balloons, a direct result of the Trump administration's cuts to the Department of Government Efficiency, has left a void in crucial weather information. This shortage could have significantly impacted the accuracy of storm predictions, potentially costing lives and resources.
Weather balloons, usually launched twice daily, are essential for gathering data on wind, temperature, and humidity. This data feeds into sophisticated computer models, enabling meteorologists to forecast the weather. However, as Typhoon Halong approached Alaska, there were barely any balloons to collect the necessary measurements.
The initial model projections placed the worst conditions further south and west, but the storm's path and intensity were not accurately predicted. The National Weather Service's (NWS) Global Forecast System (GFS) consistently showed a stronger storm in a different location. The communities that experienced the worst flooding were not even in the original forecasts.
NWS forecasters in Alaska issued warnings, but without the benefit of precise model projections made days earlier. The gaps in balloon coverage in this region are well-documented and could also affect forecasts in the contiguous United States.
Meteorologist Rick Thoman highlights the issue: "All of the systematic losses are in western Alaska." Currently, there are no balloon launches in specific locations, and other areas have reduced launches, impacting the amount of data available.
The storm's impact was felt over 400 miles southwest of Anchorage, with wind gusts exceeding 100 mph. Tragically, the storm claimed at least one life in Kwigillingok, and several people remain missing. The US Coast Guard is leading rescue efforts, with helicopters evacuating residents from flooded and damaged areas.
A NOAA official, speaking anonymously, acknowledged that the lack of balloons didn't help the forecast, although Alaska's predictions also rely on data from Asia. The official admitted that the GFS model's errors were within the average range, but other models also had significant inaccuracies.
The question remains: How much did the missing balloon data contribute to the forecast errors? Conducting a data denial experiment could provide an answer, but this is impossible without the missing data. The impact of the data gap on model performance is uncertain, leaving room for speculation.
But here's where it gets controversial: Was the Trump administration's decision to cut funding for weather balloons a factor in the forecast's shortcomings? Could this have been prevented with better data collection? These questions are sure to spark debate. And this is the part most people miss: The impact of data gaps on weather forecasting is a complex issue, and it's crucial to understand the potential consequences for future storms.
