Now satellites are helping to forecast the weather. They are in space, and they can reach any part of the world. The satellites take pictures of the atmosphere because this is where the weather forms. (a)They send these pictures to *the weather stations*. So meteorologists can see the weather of any part of the world. (b)From the pictures, *the scientist* *can often say* how the weather will change. Today, nearly five hundred weather stations in sixty countries receive satellite pictures. When they receive new pictures, the meteorologists compare them with earlier ones. Perhaps they may find that the clouds have changed during the last few hours. This may mean that the weather on the ground may soon change, too. (c)In their next weather forecast, the meteorologists can *say this*. So the weather satellites were invented, the scientists could forecast the weather for about 24 or 48 hours. Now they can make good forecasts for three or five days. Soon, perhaps, they may be able to forecast the weather for a week or more ahead.
I am not sure whether this article was written or proofread by a native speaker or not. I just find something odd in it.
(1)In sentence a, I think the THE before "weather stations" should be deleted. Am I right?
(2)In sentence b, I think the THE before "scientist" should be deleted. Am I right? Is "can often say" in the correct order?
(3)In sentence c, I think it's very odd and unnatural with the choice of words of "say this". Am I right?
(4)Is there anything else odd or wrong with this article?
Thank you so much!
