What is the forecasted wind direction, speed, and temperature over ELY at 30,000 feet?

The correct choice indicates that at 30,000 feet over Ely (ELY), the forecasted wind direction is 220 degrees, with a speed of 35 knots, and a temperature of -33 degrees Celsius. This answer reflects typical conditions found at cruising altitudes in the atmosphere.

In aerodynamics and aviation operations, wind directions are expressed in degrees, based on true north, where 0 degrees is north, 90 degrees is east, 180 degrees is south, and 270 degrees is west. A wind direction of 220 degrees suggests a west-southwest flow, which is common in certain meteorological patterns, particularly when there are significant weather systems influencing the area.

The wind speed of 35 knots is also within a normal range for high altitudes, where winds can often be stronger due to fewer obstacles compared to ground level.

The temperature of -33 degrees Celsius at this altitude aligns with standard atmospheric conditions, where temperatures typically drop as altitude increases. At cruising levels like 30,000 feet, it is not unusual to see temperatures in the negatives due to the thinning atmosphere.

These parameters are crucial for flight planning, as they directly affect aircraft performance, fuel consumption, and flight safety. Understanding these conditions helps dispatchers and
