THE EFFECT OF EL NINO AND DIPOLE MODE ON INDEX OF RICE FARMING AND RICE PRODUCTION RESULT BASED ON THE LEVEL OF THE SURFACE SEA IN WEST TIMOR

Abstract

Global warming has an impact on climate variability that causes changes in rain patterns, shifts in
seasons and impacts on crop failure. The phenomenon of climate variability is usually associated with the
El Nino and Dipole Mode phenomena which have an impact on changes in rainfall and food production.
Topographical conditions also contribute to weather and climate variability, especially in the Timor Barat
region. Agricultural Rainfall Index At an altitude of 0 - 600 meters in West Timor, the phenomenon of
El Nino, SOI neutral and neutral IOD will affect the Agricultural Rainfall Index. While at an altitude of
601 - 1200 meters the neutral IOD phenomenon affects the Agricultural Rainfall Index. The effect of
rainfall will reduce agricultural production in Belu, TTU and TTS Regencys by 0.004 to 0.005 tons, while in
Kupang the rainfall will also increase the amount of agricultural production by 0.087 tons.
