Getting caught in the rain is one of the discomforts of weather, particularly when unanticipated. When rain is driven by winds, it can be pushed into spaces intended to be dry. Depending on the nature of the space, the wind driven rain can at best be slightly disruptive. However, at the extreme end, wind driven rain interferes with sports activities, compromises electrical equipment, damages flooring and reduces revenue for semi-outdoor restaurants.

It is possible to predict the trajectory of rain and implement mitigation. To do this, one needs to understand the physics of falling droplets, the aerodynamics of wind around buildings, the statistics of rain occurrences and the nature of the space to be protected. This seminar will cover all of these aspects. Case studies will be used to demonstrate how rain penetration can be managed. Different mitigation strategies will be shown, and the dangers of cursory approaches highlighted.

Learning Objectives:

  1. Understand how rain and wind statistics are coupled.
  2. Describe the aerodynamics of rain droplets.
  3. Employ screening calculations on rain trajectories.
  4. Identify different mitigation strategies.
