Weather

3. the occurrence of a natural electrical discharge of very short duration and high voltage
4. Instrument designed to measure the speed of the wind.
5. (process) A thermodynamic change of state of a system in which there is no transfer of heat or mass
6. he perceptible natural movement of the air, especially in the form of a current of air blowing from a particular direction.
8. clouds covering a large part of the sky
9. Transport of an atmospheric property solely by the mass motion of the atmosphere.
11. a sudden brief increase in wind speed
12. stream. a narrow variable band of very strong predominantly westerly air currents.

1. a cloud that touches the ground
2. Wind An upslope wind usually applied only when the wind is blowing up hill or mountain as the result of local surface heating, and apart from the effects of the larger scale circulation.
4. Chart: A thermodynamic diagram with temperature as abscissa and pressure as ordinate.
5. Transport of an atmospheric property solely by the mass motion of the atmosphere.
7. the turning of a south or southwest surface wind with time to a more east or southeasterly direction
9. (process): A thermodynamic change of state of a system in which there is no transfer of heat or mass (i.e. compression results in warming, expansion in cooling).
10. detached, individual, cauliflower-shaped clouds usually spotted in fair weather conditions
