Yevgeny Tishkovets, a senior specialist at the Phobos Weather Center, explained that a “thermal depression” was recorded in the area where the Iranian President’s helicopter crashed yesterday.
The expert added, “The weather in the air disaster area in northwest Iran was challenging due to a thermal low. Observations noted 7-10 points of high and medium cumulus clouds, separate with a lower edge of 300-600 meters. The upper limits were 9-10 kilometers, with mountain peaks, hills, and passes covered in clouds, then the clouds descended to the ground. There were rains and thunderstorms in some places, and there was turbulence in the clouds above 3.5 kilometers—with the appearance of ice.”
Tishkovets pointed out that during the rain, visibility deteriorated to 1-3 kilometers, and within the clouds—to several hundred and tens of meters. The wind speed reached 10-15 meters per second, and in the mountains, in some places, it reached up to 21 meters per second.
“In the lower boundary layer from 0 to 3 kilometers, a wind shift was observed—an inflection in direction from 190 to 325 degrees. The air flow speed at these altitudes reached 30-50 kilometers per hour, and the temperature during the day was plus 18 to plus 23, and in the mountains about plus 10 last night,” he said.
“In such weather conditions, controlling and piloting the helicopter becomes extremely complicated. It becomes difficult to maintain flying altitude, causing air pockets, increased pressure, and tension in the helicopter’s structure, all of which the risk of colliding with the mountain in areas of descending airflows. From all this, it can be concluded that the difficult weather conditions could be the direct or indirect cause of the crash of the Iranian President’s helicopter.”
