All our weather is carried by the wind...

They don't. The trade winds are the winds blowing from the sub-tropical ridge towards the equator. They are deflected by the Coriolis effect and are therfore southeasterlies in the southern hemisphere and northeasterlies in the northern hemisphere.
When the trade winds get near the equator they help to feed moisture into the ITCZ as has already been explained but for the most part, the trade winds bring mainly fine weather. They will bring showers to an east coast but they are not noted for heavy rain unless they are augmented by another system.

Where the trade winds merge (near equator but not exactly) it's called the ITCZ (intertropical convergence zone). Because the winds converge, there is lifting and as a result, convection. You can see the ITCZ on global satellite as a line around the cloud of "dots" or convective cells. I think since the winds have a large fetch of warm, moist ocean before reaching land, this would result in heavy rains.

Because typhoons start usually at trade winds.
