Strange wind weather engine behaviour

[Topper81]

Hello I observed sometimes when starting a mission in raining conditions, some fast moving "micro clouds". Sometimes it feels to me that there is also a wind effect which should not be there (regarding to mission editor settings) but I'm not sure, maybe it's just a vidsual effect. I also noticed this issue sometimes in DCS 2.5 so it might not be related to the new clouds.

 

I cannot reproduce the issue however, it just happents sometimes on mission start. However, I noticed that by zooming out upward into the sky and back, the clouds has stopped moving so fast.

 

Please also check if those wrong wind affect can corupt track files because this is sometimesmy feeling

Ok so after further investigation I guess I'm able to reproduce the isse:

- Open the attached mission and just fly straight ahead with maximum speed and barometric altitude hold (Full afterburner)

- After one and a half minute or so, swap to the carrier view (I don't know if this is mandatory). Note that clouds and rains are moving as expected, then exit the mission

- Set "Arial-1-1" as player aircraft

- Start the mission again without saving it

- Note that clouds now moving from starboard to port (Wind comes from starboard? Wind comes from flight direction of "Arial 2-1" of the previous flown mission?)

- zoom out as far as possible straight up

- zoom back to the carrier, note that clouds now moving from bow to stern (Which might be the right behaviour regarding to the wind direction set in the mission editor)

 

I also noticed that even the rains falls in wind direction, so it's not only relate to those micro clouds:
As you can clearly see at 1:22, the rains falls from left to right. After zooming out and back at 1:43, you can see the rain falls correct from bow to stern.

In your video, it looks like the cloud motion is scheduled to the direction of travel of both the aircraft, and the carrier. In less I’m missing something, I don’t see much wrong here.
 

Remember that the wind direction in DCS (the ME and reported by ATC) is reversed compared to real life wind reporting standards. It indicates the direction the wind is blowing towards rather then the direction it is coming from. (This really needs to be changed as the weather system is improved.)

 

In DCS to set a northerly wind, usually reported as 360°, the wind need to be set to 180° in the ME.

There is defenetly someting wrong.. PLease look at the direction the rain is falling at 1:30 and at 1:50, and it jus changed because zooming out and in again with the camera. Please read also my description: The previous steps where just to reproduce the issue.
