Cloud suck The telltale signs for a pilot climbing in the thermal under a "sucking" cloud are (1) lift strengthening, (2) lift getting smoother, and (3) widening of the thermal. Paraglider pilots have reported being unable to descend in strong cloud suck, even after bringing their canopies into deep spiral, which would normally result in a rapid vertical descent. Cloud suck is especially dangerous for paraglider pilots, whose maximum speed is less than 30 knots, because storm clouds (Cumulonimbus) can expand and develop rapidly over a large area with accompanying large areas of strong lift.

Cloud testing testing. Using cloud environment, instances of different Operating Systems can be created on demand, making compatibility testing effortless. To verify application's support for various browser types and performance in each type can be accomplished with ease. Various tools enable automated website testing from the cloud. Cloud testing is utilized to measure the latency between the action and the corresponding response for any application after deploying it on cloud. Companies simulate real world Web users by using cloud testing services that are provided by cloud service vendors such as Advaltis, Compuware, HP, Keynote Systems, Neotys, RadView and SOASTA.
