“Because the anvil from that cell is spreading downwind—right over Rome’s ILS localizer. That means low-level wind shear and possible microbursts on the go-around. We don’t have the fuel to play guessing games.”
ATPL Meteorology Question 3: In the Northern Hemisphere, where is the area of most significant divergence aloft relative to a jet streak? meteorology atpl questions
Runway visual range below 150 meters. Freezing fog. Vertical visibility 100 feet. The airport was closed. “Because the anvil from that cell is spreading
Jim nodded. “And the pressure trend?” Runway visual range below 150 meters
“It’s a classic temperature inversion aloft with a shallow sub-zero surface layer,” Maya said, thinking out loud. “The cloud tops are warm—above zero—but the precipitation falls through a cold layer below. That’s supercooled droplets. On impact with the airframe…” She glanced at the wing anti-ice lights. Green. Still working.
“It’s a warm front,” Maya said, running the mental checklist. “Pressure has dropped 4 hPa in the last three hours. Wind has veered from 160 to 210. That’s classic warm front advection. But Captain, the METAR is reporting visibility 800 meters in freezing drizzle, ceiling indefinite… they’re calling it vertical visibility 100 feet .”
