Further complicating the use of these proxies is the fact that the deviation
in oxygen - 18 ratios is affected by the amount of TC
rainfall, the distance from the center of the cyclone at which the rain was produced, and the
intensity of the cyclone — so I doubt these proxies alone will enable disentangling
intensity and
rainfall, tnough a large number of samples over an area could reveal information about the track and extent of the TC event.

rainfall rather than the
intensity.

in this region, and for the possibility that the
intensity and frequency of such events might change
in the future as the climate continues to warm.
Over the coming decades, Atlantic hurricanes are likely to increase
in strength as sea surface temperatures increase, fueling the
