careful detailing of vapor barrier locations in air-conditioned buildings.
Common building materials that exhibit hygroscopic properties such as gypsum,
insulation, and particle board can lose their structural and functional
properties in humid climates.

Intense Rain Periods. For those tropical areas that have prolonged
rain periods, specify soil treatments in addition to water infiltration
control. Consider and avoid structural instability and exacerbation of rust
and decay due to possible water infiltration of buildings. Because tropical
areas often experience brief, intense rainfall producing flood conditions,
include provisions for and consideration of ponding and runoff conditions.

Monsoons. These are wind systems on a continental scale which
seasonally reverse their direction because of a change in temperature trends
over land and sea. Generally, winds blow from cold to warm regions; for
example, sea to land in summer and land to sea in winter. This occurs because
atmospheric pressure is high in cold regions and low in warm regions.
