    In a light aircraft, an increase in rate of climb can be caused by an updraft like you might find down low over a plowed field, or from entering convective activity, or from a sudden increase in headwinds (wind shear) like when near a thunderstorm.

    When landing, a “sudden decrease in the headwind component”, if it is extremely fast, will show on your instruments as a sudden decrease in airspeed. That is called ‘wind shear’. When shear is being reported at your destination, you should maintain your normal landing speed plus 1/2 the gust factor to give yourself a buffer against an inadvertent stall. For example, if the wind is reported 12 knots with gusts of 8 knots, you should add half of 8 or 4 knots to your normal landing speed.

    FAA-H-8083-25B Pilots Handbook of Aeronautical Knowledge has a good explanation of this with diagrams that helped me understand it. It is on page 12-11 of the current version. If you want to find out more, AC 00-54 Pilot Windshear Guide, is a thorough explanation of shear. Don’t be put off by the date (1988). Even though it is old, it is still accurate and easy to follow.
