Weather
Prior to takeoff; we briefed the departure and completed checklists for Runway XX per the SID with updated ATIS. The weather was: (N) November wind forecast at 050/9; 9 miles visibility with rain; overcast at 600 feet temperatures 6/4; altimeter 29.72' Per the SID; we climbed runway heading to 150 AGL then went to NAV mode to join the SID on a heading of 334 degrees; At 600 feet; I called for autopilot on; a few seconds later in the turn at about 700 feet in the clouds and heavy rain; the WINDSHEAR alarm sounded. The autopilot kicked off and I executed the windshear emergency procedure by applying full power; maintaining heading and following the flight director for maximum angle of attack. Per the most recent company operations bulletin posted just a few days before about Prohibited Area violations; the First Officer called the Tower immediately and advised 'windshear event'. The Tower acknowledged and advised other traffic. The windshear alarm continued for 10-15 seconds as I continued to following the emergency procedure. After the event; [we] contacted the Tower and they had us switch to Departure; also advised them of our current heading and altitude and the windshear event. We tried to rejoin the SID and the departure; understanding the nature of the [situation]; Departure gave us a 120 degree heading to rejoin the SID after ZZZZZ. Once established; we climbed to 14;000 feet at 250 knots. We were later told to contact ZZZ Operations when we landed. When we called the Operations Director after landing; he advised us that they had pulled the data and recorded the windshear as changing from 050/8 on the surface to 150/37 at 1;000 feet. He stated he was glad of the outcome (we were still alive) and took my information. He stated we had done the right thing and we would be contacted for additional information in about a week.
