Characteristics
In subtropical climates the winters are relatively warm-mild, but not as hot as the summer season. These climates rarely—if ever—see frost or snow and plants such as palm, citrus and many broadleaf evergreens flourish, in contrast to the hardier deciduous and coniferous trees which dominate midlatitude climates. As one moves toward the tropical side the slight winter cool season disappears altogether, while at the poleward threshold of the subtropics the winters become much cooler.
Rainfall patterns vary widely throughout the subtropics including hot deserts, savannas, monsoon forests, humid forests and the warmer parts of the Mediterranean climate zone. Subtropical regions include most of California and southern Europe (Mediterranean or dry-summer subtropical climate), the low deserts of the Southwest USA (hot arid type), the Gulf Coast and most of Florida (humid subtropical climate), northern India (monsoon), southeast China, Taiwan and Japan (humid), the middle part of South America (varied), much of Australia (varied) and coastal South Africa.
