Meteorologists say that if only they could design an accurate mathematical model of the atmosphere with all its complexities, they could forecast the weather with real precision. But this is an idle boast, immune to any evaluation, for any inadequate weather forecast would obviously be blamed on imperfections in the model.

(A) The amount of energy that the Earth receives from the Sun is monitored closely and is known not to be constant.

(B) Volcanic eruptions, the combustion of fossil fuels, and several other processes that also cannot be quantified with any accuracy are known to have a significant and continuing impact on the constitution of the atmosphere.

(C) As current models of the atmosphere are improved, even small increments in complexity will mean large increases in the number of computers required for the representation of the models.

(D) Frequent and accurate data about the atmosphere collected at a large number of points both on and above the ground are a prerequisite for the construction of a good model of the atmosphere.（B）

(E) With existing models of the atmosphere, large scale weather patterns can be predicted with greater accuracy than can relatively local weather patterns.

这题我选D..请问D错在哪?又为何是B呢???谢谢

(B)说Volcanic eruptions会引响气候又无法数量化，所以机器再准确也无法预测，因此weaken meteorologists

可是(D)说要做出新的model要先收集大量的准确的气候资料，不也说明新的机器在没有准确的数据前提下，不会更精准，因此weaken meteorologists

吗?

另外，想再请问E的relatively local weather patterns在这里该如何理解呢?我看起来E好像是说:用别的模式操作的话，目前的机器就会更精准

Meteorologists say that if only they could design an accurate mathematical model of the atmosphere with all its complexities, they could forecast the weather with real precision.

只要他们能够设计出准确的数据模式，他们就能够准确的预测天气。

D 说： Frequent and accurate data about the atmosphere collected at a large number of points both on and above the ground are a prerequisite for the construction of a good model of the atmosphere.大量收集准确的大气数据，是一个好的模式建设的前提。

我觉得D 没有起到削弱的作用。这倒是有点加强的意思了。个人认为。
