First, enable link state propagation on the radios if you haven't already,
so that when the link is totally out (in a bad rain storm) it will bring
down the optics simulating a cut fiber cable. The rest depends on how
diverse the paths in and out of that site are.

If both links are in parallel with each other on the same path, they should
fade equally, except for the raindrop difference between H and V if you're
running this as a setup with four radios + two OMTs + two dishes.

Assuming you have a manually configured OSPF cost for a 10GbE link on the
router interfaces on both sides of the link, dealing with a link that
changes data rates (and therefore its OSPF cost) proportionally with its
current modulation rate can be tricky.

If I had to do it, I'd write some custom shell script or python that ran on
a trusted internal network system, watching an SNMP OID on the radios on
both ends for current modulation rate (example: SNMP poll result of 2 = 4
Gbps, 5 = 6 Gbps, 6 = 10Gb full data rate). Then use the results from that
SNMP poll to, in a fully automated way, maintain a persistent ssh session
to the routers on both ends of the link and change both ends' OSPF
interface costs on the fly, repeatedly, until the rain fade event had
passed. This could be done at 5-second intervals.
