downwind in the direction of the wind Explanation: Upwind is an antonym of downwind. Downwind is an antonym of upwind. As adverbs the difference between downwind and upwind is that downwind is in the same direction as the wind is blowing while upwind is in the direction from which the wind is blowing. http://wikidiff.com/downwind/upwind 1.)Down Wind = The wind is blowing away from you. You are moving with the direction of the wind/current. 2.)Upwind = Toward or against the wind or the direction from which it is blowing. You are moving into/against the wind/current. It is in your face. http://www.fieldandstream.com/answers/quick-tips/ok-may-soun... -------------------------------------------------- Note added at 1 hr (2017-08-19 14:57:25 GMT) -------------------------------------------------- There's quite a lot of information in the following reference: http://www.njsp.org/division/homeland-security/pdf/hrmu/0608... is this related to chemical wind-borne hazards? -------------------------------------------------- Note added at 4 hrs (2017-08-19 17:59:59 GMT) -------------------------------------------------- On page 2 of the last link I posted (New Jersey Hazmat Emergency Response Course), under Course Goals it says: '...The classes that follow are designed to increase the depth of knowledge of responders who may be confronted with the challenges created if a terrorist incident were to involve the employment of nuclear, biological, chemical (NBC) agents.' At the top of page 2 of Module 3 it says: Biological Agents '...Sverdlovsk (now Ekaterinburg) was located about two and one-half miles from a then Soviet military facility. On this particular day, the wind was blowing such that Sverdlovsk was downwind from the military facility when an explosion occurred'. There are more references to 'downwind' but it would take me ages to copy all the fragments where the word appears. |
