Sudden changes in wind speed or direction, known as wind shear, can lift or smash aircraft into the ground during landing.
Those characteristics can include a brief dip in air pressure, a change in wind direction, a change in wind speed, a rise in air temperature or a dip in ultraviolet light reaching the rover.

Conventional small wind turbines only work 20 percent to 40 percent of the time due to variations in wind speed, according to the Department of Mechanical Engineering of The University of Hong Kong and Motorwave.
The mast was installed in April to measure wind speed, wave height and sea currents.
BBC: Offshore Sussex wind farm weather mast causes 999 calls
Pielke in 2008 determined that as wind speed increases, property damage increases far faster.
In particular, the sunlight and wind speed are too weak to meet a meaningful portion of the region's prodigious energy needs ... at least with today's technology.
The most persuasive evidence that Voyager 1 has crossed the termination shock is its measurement of a sudden increase in the strength of the magnetic field carried by the solar wind, combined with an inferred decrease in its speed.
Wind speed of 82mph recorded in Berry Head in Brixham, south Devon.
Change takes work and creativity, much like how a roller coaster needs to climb up that first steep hill, but the reward is the thrill of the speed and the wind in your face on the way down.
Also, changes in the speed and pressure of the solar wind cause the termination shock to expand, contract and ripple.
In the event, Cristobal's command of wind speed proves inadequate and the first batch of poems is carried away from the crowd, sending people scurrying through side streets in pursuit of poetry.
While the fires still threatened some 25, 000 homes, the burn rate in the region -- a measure made up of factors like wind speed, humidity and available fuel -- was significantly lower Thursday, a spokeswoman at the California Department of Forestry and Protection said.
CNN: Firefighters gain ground in California, but death toll rises
The assumptions of a 230 mph wind speed and a 1.2 psi rapid pressure decrease in about 1 second along with large and fast missiles is quite a force to design against.
It is only in the Pairs Match that each competitor can have a coach providing information on wind direction and speed.
We used the Recovery Act to provide seed money that sparked private investment -- private investment in new industries like solar and wind, advanced batteries, high-efficiency lighting, high-speed rail.
Wind power has made significant advances in efficiency and scale in recent years, but wind-turbines are still able to handle only one of many wind-speed categories.
The energy released in the updrafts then interacts with our second ingredient needed for violent tornadoes, the change of the wind direction and speed at you go upward from the ground.
Given the likely direction of the new GOP-dominated House of Representatives in Washington, massive federal subsidies for the solar and wind industries, as well as such boondoggles as high-speed rail, are likely to be scaled back significantly.
