The climate data (mean monthly temperature and rainfall) of a specific place is described below. This data is indicative of which one of the climatic zones of the world?

Month	J	F	M	A	M	J	J	A	S	O	N	D
Temp (°C)	22	24	27	30	32	30	28	27	27	28	25	22
Rain (cm)	0.2	0.3	1.0	2.5	10.5	25.0	32.0	28.5	15.0	5.0	1.0	0.3

OPTIONS:
A) Wet and dry tropical
B) Rainy tropical
C) Semi-arid tropical
D) Temperate marine

The plotted climate—uniformly high mean monthly temperatures with a pronounced rainfall peak in a few months and a distinct dry winter—matches the Tropical wet-and-dry (savanna) or Aw climate. Aw is characterized by high year-round temperatures (coldest month >18°C) and rainfall concentrated in the southwest monsoon with dry winters [1]. Koppen-type listings explicitly separate Af (no dry season), Am (monsoon), and Aw (wet and dry/savanna) with Aw noted for distinct wet and dry seasons [2]. The graph’s clear seasonality in precipitation rules out Af (rainy tropical), which has significant rainfall every month, and also differs from semi-arid or temperate marine patterns, so option 1 is correct [3].
