High rain totals are represented in dark blue, while small rainfall totals are shown in white. The most obvious pattern in the total rainfall maps is seasonal change. A band of heavy rain moves north and south of the Equator seasonally.

Feb 4, 2025 · This indicator examines U.S. and global precipitation patterns, based on rainfall and snowfall measurements from land-based weather stations worldwide. This indicator starts at 1901 except for the detailed map of Alaska, where reliable …

Short range forecast products depicting pressure patterns, circulation centers and fronts, and types and extent of precipitation. 12 Hour | 24 Hour | 36 Hour | 48 Hour

Rainfall patterns can vary greatly from region to region, with some areas receiving very little rainfall while others experience frequent heavy downpours. Different types of rain include frontal rain, convective rain, and orographic rain, each of which is …

Oct 19, 2016 · Jump in and play with the data yourself! The tables below list the ten wettest and ten driest locations in the United States. Again, these are annual normals, or what would be expected in the mythical “average” year.

Nov 12, 2013 · Climate models predict that the addition of heat-trapping gases in the atmosphere will shift precipitation in two main ways. The first shift is in a strengthening of existing precipitation...

Rainfall patterns refer to the distribution and frequency of precipitation across various regions of the Earth, influenced by global atmospheric processes. In tropical areas, warm air holds significant moisture, which condenses into rain as it rises and cools. This moisture-laden air moves towards latitudes around 30° north and south, where …

These anomalies in sea surface temperature are mirrored in rainfall patterns, with warmer-than-normal temperatures resulting in enhanced rainfall. In general, La Niña brings unusually heavy rain to the West Pacific, Indonesia, parts of Southeast Asia, and northern Australia.

The geographic pattern of precipitation is explained by examining the spatial distribution of air masses, water availability through evaporation, and uplift mechanisms. One of the most important climate elements is the influence of the global pressure systems.
