In a surprising turn of events on April 13, 2022, the Russian guided missile cruiser Moskva faced explosions in the Black Sea, more than 100 kilometers south of Odesa, Ukraine. Despite being outside the typical range of Ukrainian missile radar, the cruiser sank as it was being towed to port, with Ukraine claiming responsibility for the attack. A recent study, published in the Bulletin of the American Meteorological Society, suggests that anomalous atmospheric conditions might have played a pivotal role in extending the range of Ukrainian missile radar, enabling the successful targeting of the Moskva.
Lt. Col. Andreas Grantinger, a meteorologist with the Swedish Armed Forces weather service, emphasizes the significance of understanding such anomalies in military operations. He notes that these conditions are not uncommon, particularly in the Mediterranean, and can occur sporadically in other regions.
Initially, Russian sources attributed the Moskva's explosions to an accident, while Ukraine insisted on using R-360 Neptune antiship missiles fired from a coastal battery. However, the cruiser was significantly beyond the range of the missile system's targeting radar.
Speculation arose about possible U.S. involvement, with analysts suggesting that a U.S. military aircraft may have guided Ukraine. The study's lead author, Lars Norin of the Swedish Defence Research Agency, dismisses this theory, considering it a substantial escalation that the U.S. was likely to avoid.
The intriguing aspect of the story lies in a report by Ukrainska Pravda, indicating that unusual weather conditions allowed Ukraine to detect the Moskva using the Neptune's Mineral-U search-and-track radar. Lars Norin's team used a wave propagation model to investigate this phenomenon, considering the radar's ability to detect the ship beyond the usual horizon.
The study suggests that on the specific day, cyclonic winds created a temperature inversion over the Black Sea, causing low-level clouds to form along the radar's line of sight to the warship. This allowed the radar's signals to follow Earth's curvature over an extended distance. The scientists conclude that the targeting occurred when atmospheric propagation conditions permitted detection.
While there is no known precedent for such anomalous atmospheric conditions aiding radar in targeting a military object so far over the horizon, experts emphasize the importance of considering weather factors in military operations. Understanding and adapting to these conditions become crucial elements in maintaining operational security.
As military meteorologists grapple with evolving challenges, including those posed by climate change, staying abreast of atmospheric phenomena remains imperative. The study sheds light on the intricate interplay between weather conditions and military strategies, underscoring the need for ongoing vigilance in the face of dynamic environmental factors.
