What would be the correct entry in Column 4 (Speed) of MF1M-10 for wind from 360° at 125 knots?

The correct entry for wind speed in Column 4 of the MF1M-10 form requires the speed to be expressed in whole knots without any additional letters or symbols. When reporting the wind speed, the value is presented simply as a number. Therefore, recording "125" accurately communicates the wind speed of 125 knots.

Using just the numerical value aligns with standard reporting practices, ensuring clarity and compliance with meteorological conventions that focus on straightforward numerical data input for wind speed. Options that include letters or additional information, such as "KT" or "KTS," would not be appropriate in this context where only the numeric value is needed.
