A great portion of the world's deserts are located within the subtropics, due to the development of the subtropical ridge. Within the humid monsoon regions in the subtropics such as Northern Vietnam (including Hanoi), a wet season is seen annually during the summer, which is when most of the yearly rainfall falls.
A great portion of the world's deserts are within the subtropics, as this is where the semi-permanent subtropical anticyclone resides (typically inland on the southwest sides of continents). Areas bordering warm oceans (typically on the southeast sides of continents) have hot and wet summers with frequent (but brief) convective rainfall ...

Tropical deserts are located in regions between 15 and 30 degrees latitude. The environment is very extreme, and they have the highest average monthly temperature on Earth . Rainfall is sporadic; precipitation may not be observed at all in a few years.
The Sonoran Desert is clearly distinct from nearby deserts (e.g., the Great Basin, Mojave, and Chihuahuan deserts) because it provides subtropical warmth in winter and two seasons of rainfall (in contrast, for example, to the Mojave's dry summers and cold winters). This creates an extreme contrast between aridity and moisture.
The Thar Desert, also known as the Great Indian Desert, is an arid region in the north-western part of the Indian subcontinent that covers an area of 200,000 km 2 (77,000 sq mi) in India and Pakistan. It is the world's 18th-largest desert, and the world's 9th-largest hot subtropical desert.
The Arabian Desert has a subtropical, hot desert climate, similar to the climate of the Sahara Desert (the world's largest hot desert). The Arabian Desert is actually an extension of the Sahara Desert over the Arabian peninsula. The climate is mainly dry. Most areas get around 100 mm (3.9 in) of rain per year.
To delineate "hot desert climates" from "cold desert climates", a mean annual temperature of 18 °C (64.4 °F) is used as an isotherm so that a location with a BW type climate with the appropriate temperature above this isotherm is classified as "hot arid subtype" (BWh), and a location with the appropriate temperature below the isotherm is ...
