Rain largest increases are in the Northeast and Midwest, which in the past decade, have seen 31 and 16 percent more heavy downpours compared to the 1950s. Rhode Island is the state with the largest increase, 104%. McAllen, Texas is the city with the largest increase, 700%. Heavy downpour in the analysis are the days where total precipitation exceeded the top 1 percent of all rain and snow days during the years 1950–2014 The most successful attempts at influencing weather involve cloud seeding, which include techniques used to increase winter precipitation over mountains and suppress hail.

Reindeer hunting in Greenland there can be cornices, crevasses, and avalanches, although snow can make it easier to spot and track reindeer. The weather during the beginning of the autumn hunting season is often pleasant, relatively warm, and mild, but it can change very quickly. Hunters may encounter fog, rain, wind, and winter conditions. Occasionally the situation can quickly approach a worst-case scenario with events such as katabatic winds, storms, snow, hail, sleet, freezing rain, blizzards, and polar cyclones, even in the late summer. Lack of preparation can have fatal consequences. Using a compass in Greenland involves accounting for a very extreme magnetic declination.
