6 hours.

• B.

1 hour.

• C.

3 hours.

• D.

12 hours.

B. 1 hour.
Explanation
The correct answer is 1 hour. This is because METARs (Meteorological Aerodrome Reports) are typically issued every hour. These reports provide information about the current weather conditions at an aerodrome, including temperature, wind speed and direction, visibility, and cloud cover. The frequent issuance of METARs allows pilots and air traffic controllers to have up-to-date and accurate weather information for flight planning and safety purposes.

### METAR  CYWG 071500Z 34008KT 15SM SKC M24/M28 A3043 RMK SLP332= According to this METAR report, what is the temperature range between current temp and dew point in Winnipeg;

• A.

30 degrees c

• B.

15 degrees c

• C.

4 degrees c

• D.

-4 degrees c

C. 4 degrees c
Explanation
The METAR report provides information about the temperature and dew point in Winnipeg. The current temperature is given as -24 degrees Celsius (M24) and the dew point is given as -28 degrees Celsius (M28). To find the temperature range between the current temperature and the dew point, we subtract the dew point from the current temperature: -24 - (-28) = -24 + 28 = 4 degrees Celsius. Therefore, the temperature range between the current temperature and the dew point in Winnipeg is 4 degrees Celsius.
