-vector_dir¶

Introduction¶

Bit 5 of the flag 3.3 indicates whether vector quantities are relative to the grid or the North/South poles. The -vector_dir option writes out "winds(N/S)" or "winds(grids)" depending on the value of the flag. Note there is no flag that indicates whether the quantity is a U/V component of a vector.

Usage¶
