Warm current (2,4)

Ross

I believe the answer is:

el nino

<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">warm current</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is the entire clue.<br/ ></span>

(Other definitions for el nino that I've seen before include "modern opera" , "Periodic warming of the eastern Pacific Ocean" , "Pacific climatic feature" , "Warm current affecting world's climate" , "Pacific climatic effect" .)

I've seen this clue in The Telegraph.
