WIND SHEAR WARNINGS — EXAMPLES OF ELEMENTS

Non-exhaustive examples of the different elements used in the formulation of wind shear warnings are provided below.

| Wind shear warnings — examples of elements Note 1: Consult the ‘Template for wind shear warnings’ (Appendix 4 to Annex V (Part-MET) to Regulation (EU) 2017/373) to identify the mandatory (M), the conditional (C) or the optional (O) elements. Note 2: The ranges and resolutions for the numerical elements included in wind shear warnings are provided in Appendix 8 to Annex V (Part-MET) to Regulation (EU) 2017/373. Note 3: The row numbers in the ‘Ref.’ column are included only for clarity and ease of reference, and are not part of the wind shear warning. They do not correlate with the ‘Ref.’ column in the ‘Template for wind shear warnings’ of Appendix 4 to Annex V (Part-MET) to Regulation (EU) 2017/373. Refer to the ‘Element’ column when cross-referencing. |                                           |                                                                              |
