Land of stormy rain (4)
I believe the answer is:
iran
'land' is the definition.
(I know that Iran is Asian country)
'stormy rain' is the wordplay.
'stormy' indicates anagramming the letters (stormy suggests disruption).
'rain' is an anagram of 'IRAN'.
'of' is the link.
(Other definitions for iran that I've seen before include "Country where the official language is Farsi" , "bombless state" , "Country of western Asia" , "Tehran is its capital" , "Modern Persia (4)" .)
