Wind shear (WS) is one of the main adverse phenomena for air navigation, improving the most critical phases of flight (takeoff and landing). In such, a procedure manual for forecasting Clear Air Turbulence (CAT) was prepared and associated WS at the Cusco aerodrome, for which a case study was carried out on June 9, 2018 in Cuzco-Peru. Collecting METAR information, meteorological data from the Automated Weather Observation System II (AWOS II) and extraordinary aircraft observations, simulations of the Weather Regional Forecast (WRF) model were also carried out at 12 hours (12 to 23 Z) to perform a synoptic analysis of WS and CAT, by calculating estimated value of WS and CAT and identifying patterns of CAT occurrences. For the synoptic analysis of WS and CAT, the occurrences of vertical WS of 8 knots (kt) were observed on the approach of the aircraft (600-550 hPa); and values of 17 and 10 kt in the vertical and horizontal components of WS, respectively, at higher levels (200 hPa). using the Vertical Wind Shear outputs. Likewise, the probable occurrence of CAT with estimated values between 6 and 8 of the Ellrod index. According to the results, the genesis of CAT is mainly due to confluent jets with diffluent wind patterns at higher levels (200 hPa) accompanied by very intense winds at the 500 hPa level. Finally, the stated procedure was systematized using a flowchart in order to provide the forecaster of the Cusco Aerodrome Meteorological Office (OMA SPZO), tools and decision criteria for the early issuance of Non-Convective WS warnings forecast for the Cusco airport.
