Shooting landscape does place you almost entirely at the mercy of the weather, time of year, etc. to find good lighting.
At least in my experience, it's a bit more opportunistic -- instead of deciding exactly what you want and forcing that to happen, it's a lot more about picking a time when the light is nice, and finding the subjects that happen to be nicely lit at that time. To a limited degree, greater experience does lead to more control though. It's still not really control over the lighting, but you control where you go and when you go there, to maximize your chances of finding particularly nice light on interesting subjects.
I haven't had time lately, but used to keep a notebook where I tried to track (reasonably) specific times to visit particular locations (e.g., wanting to go to a particular valley a few hours before sunset close to mid-winter so the sun would well low in the sky to the south-west).
The three shots you've posted above all look like they were taken at least fairly close to the middle of the day in "nice" weather. Although it may initially seem like the obvious time to take pictures, I (for one) find it relatively difficult to get really satisfying pictures under those conditions. Simply taking pictures at other times often gives much better results. Three obvious possibilities are right around sunrise and sunset, and immediately after a storm. you obviously don't have to restrict yourself to shooting at those times, but I think it's worth giving some of them a try.
