Sunlight passing through the car's windshield produces the greenhouse effect, heating the interior to a temperature much higher than the outside air. Without any protection, the sun can heat up a car's dark dashboards to 69 °C (156 °F) within 60 minutes. [6] This is dangerous for adults, children, and animals.
Here, the total score may be accepted even though some of the results had a tail wind of more than 2.0 m/s. In events where wind velocity is measured, the average velocity (based on the algebraic sum of the wind velocities, as measured for each individual event, divided by the number of such events) shall not exceed +2.0 m/s (Rule 260.18). [2]
Roughness length is a parameter of some vertical wind profile equations that model the horizontal mean wind speed near the ground. In the log wind profile, it is equivalent to the height at which the wind speed theoretically becomes zero in the absence of wind-slowing obstacles and under neutral conditions. In reality, the wind at this height ...

Wind shear is also a significant factor. Linear snow squall bands produce more thundersnow than clustered bands; thus a directional wind shear with a change of less than 12° between the ground and 2,000 m (6,600 ft) in height must be in place. However, any change in direction greater than 12° through that layer will tear the snow squall apart.
Diagram of effect (in French): Vent is wind direction, Congère is snow drift, Couverture de neige is snowcover. Fir hedges as living snow fences. Temporary snow fences are usually one of two varieties: perforated orange plastic sheeting attached to stakes at regular intervals (the type usually used for construction site fencing or temporary sports field fencing) or a cedar or other ...
