Index.hrIndependentCenterFactual 95Objective 9012 days agoAn unusual radar image showing a semicircular vortex pattern over Italy, Slovenia, and Croatia circulated online, sparking confusion among users. The phenomenon was recorded around 14:30 on the Windy platform, but the Slovenian Agency for the Environment (Arso) clarified that it was not a real meteorological event but rather a data distortion in radar readings. The anomaly coincided with rainy weather and local storms in parts of Slovenia, prompting people to seek explanations online. The source of the disturbance was identified as the radar station in Italy, Fossalon. Arso confirmed that the pattern did not represent actual rainfall and noted that the exact cause was unknown, though they suggested it might be related to measurement or data processing issues. Meteorologists explained that false circular patterns on radar often result from the 'melting layer', where layers of precipitation at freezing temperatures create stronger radar echoes, leading to concentric circle projections on the ground.

Why factuality (95): The article accurately reports the explanation from Arso regarding the false radar images being caused by data interference from the Italian radar Fossalon. It also correctly describes the technical explanation of concentric circles on radar images, aligning closely with the primary source document.
Why objectivity (90): The article maintains a neutral tone throughout, presenting facts without editorializing or showing bias. It provides context and quotes from Arso without taking sides or using emotionally charged language.
N1 HrvatskaIndependentCenterFactual 93Objective 9211 days agoUnusual radar images showing apparent whirlpools of storm clouds over Italy, Slovenia, and Croatia's Istria region sparked online speculation. The images appeared on the Windy platform and were interpreted by some as evidence of a real atmospheric phenomenon. However, Slovenian meteorologists clarified that these images were not indicative of actual precipitation but rather the result of interference in radar data from the Fossalon radar station in Italy. According to the Slovenian Environment Agency (ARSO), the exact cause of the interference remains unclear but is likely related to measurement or data processing errors. Meteorologists explained that concentric circles often appear on radar screens due to the way radar scans the atmosphere using rotating antennas, which measure precipitation at different heights. These readings are then processed into maps, sometimes creating misleading visual patterns like circular waves or whirlpools. In this specific case, the unusual image was attributed to technical issues with the Italian radar system, not to any actual weather event.
Bias read (Center): The article provides a balanced explanation of the scientific and technical causes behind the unusual radar imagery, citing official sources such as the Slovenian Environment Agency (ARSO). It does not take a stance on the issue and presents the information objectively, focusing on clarifying the误会.
Why factuality (93): The article accurately presents the information from Arso about the false radar images and their cause. It includes the correct explanation of the technical process behind the concentric circles, matching the primary source document closely.
Why objectivity (92): The article is highly objective, presenting the facts neutrally and providing clear explanations without any apparent bias or emotional language.
Radar image over Croatia flooded the internet: An explanation of the mysterious vortex has arrivedOn Tuesday, August 11, 2026, users noticed an unusual radar image on the Windy portal showing swirling storm clouds over Italy, Slovenia, and Croatia’s Istria region. The image went viral online, prompting social media discussions and questions about potential weather anomalies. However, the Slovenian Environment Agency (ARSO) clarified that the circular patterns were not real precipitation but artifacts caused by data interference from the Italian radar station Fossalon. ARSO explained that such concentric circles often appear due to radar measurement techniques, where the antenna rotates and captures rainfall at different altitudes. When snow melts at temperatures around 0°C, it creates stronger radar echoes, leading to the distinct ring-like formations seen in the images.

Why factuality (92): The article accurately conveys the information from Arso about the false radar images and their origin in the Italian radar Fossalon. The explanation of the technical process behind the concentric circles is consistent with the primary source, though slightly less detailed.
Why objectivity (88): The article remains largely objective but shows a slight leaning towards emphasizing the mystery of the phenomenon before revealing the explanation, which could be seen as a minor bias toward intrigue.
