What is the wind and temperature aloft forecast for DEN at 9000 ft?

1. 210 degrees true at 21 knots, temp -4 degrees C

2. 230 degrees true at 21 knots, temp -4 degrees C

3. 230 degrees true at 21 knots, temp +4 degrees C

4. 210 degrees true at 24 knots, temp -6 degrees C

The correct answer is: 230 degrees true at 21 knots, temp -4 degrees C

For the wind and temperature aloft forecast for Denver (DEN) at 9,000 feet, the correct choice indicates that the wind is coming from 230 degrees true at 21 knots with a temperature of -4 degrees Celsius. This choice reflects a standard format for wind forecasts, which denote wind direction as the angle measured from true north, where a value of 230 degrees represents a southwest wind. The wind speed is also important, as it indicates the strength of the winds at that altitude. The forecast specifically indicates that the wind is blowing at 21 knots, which is a moderate speed, common at this altitude. The temperature of -4 degrees Celsius suggests that the air is relatively cool at 9,000 feet, which is consistent with typical atmospheric conditions as altitude increases. This condition is important for pilots to understand as temperature impacts aircraft performance, air density, and potential weather phenomena. Overall, this choice accurately represents standard meteorological information used for flight planning, ensuring that pilots can prepare for the specific wind conditions and temperature they may encounter during flight.
