But why exactly does it rain so much in the Pacific Northwest? ... When moist winds blow inland with an approaching storm, the high terrain of the Cascade Range forces the moist air to rise into the atmosphere, enhancing the thick clouds and steady rainfall.

With temperature increases, the proportion of precipitation falling as rain can be expected to increase, reducing natural storage of water. This will increase risks of seasonal flooding and scarcity, posing direct challenges for water and sanitation.

Floods are the most frequent climate-related hazard in the Dominican Republic, with the northeastern region vulnerable to floods and mudslides from severe storms, while arid parts of the northwest are experiencing increasing temperatures leading to more drought, which reduces crop yields and water supplies.

A few reasons. Upper-level winds in the atmosphere usually steer big hurricanes and keep them moving after they make landfall. With Harvey, those steering winds broke down, and a high pressure system to the northwest kept Harvey locked in place. That's why Harvey is such a catastrophic rainfall disaster.

The community lies in the shadow of the Cascade Mountains creating a hot, sunny, dry climate. For this reason, the area boasts its own climate zone called "Osoyoos Arid Biotic Zone." Canada's lowest annual precipitation, warmest annual temperature, and warmest fresh water lake can be found here.

Basically, if you get caught in a sudden rain shower, it's lightly drizzling, or you just have to run out for a couple minutes, you'll be fine in wool. If it's a torrential downpour, or you need to be outside in the rain/snow for a long time, you risk the water seeping through if it gets wet enough.

Australia fires: Rain finally falls on some bushfires. Australians are celebrating the arrival of much-needed rain in parts of the nation's bushfire-ravaged south-east. Though more wet weather is needed to end the fires, the rain has brought a welcome reprieve to many areas. Other parts, however, have not been as lucky ...

A warmer climate spurs the evaporation of water from land and sea and allows the atmosphere to hold more moisture—thus setting the stage for more extreme precipitation.

It also leads to more severe weather events over time. Increasing global temperatures causes water to evaporate in larger amounts, which will lead to higher levels of atmospheric water vapor and more frequent, heavy, and intense rains in the coming years.

The surfaces themselves often contain contaminated areas from motor oil and other pollutants. When rain occurs, the water flows over these surfaces increases and builds momentum due to the lack of resistance and absorption by plants. More land can potentially become polluted due to this toxic runoff.

When the air hits the top of the atmosphere, it spreads north and south toward the poles. It does not sink back down until it is over the subtropics, but as it does, the air warms and dries out, creating deserts and other areas that are nearly devoid of rain.

Rain doesn't affect a flight that much in itself. Obviously if combined with very heavy winds, it can cause extra considerations and challenges to flight planning – even a change of route or a delay if the conditions are extreme.

It just means that the chance of you being affected by it is very low. Often times people with regard 20 percent chance of rain as the weatherman having no clue what's going to happen.

Victoria Falls, one of the natural wonders of the world, is running dry due to climate change. Victoria Falls, known locally as Mosi-oa Tunya, (“The Smoke that Thunders”), has seen its water levels slow to a relative trickle this dry season as drought ravages the region due to the impact of climate change.

Seattle's weather is regulated by the Pacific Ocean, which remains relatively even in temperature throughout the year. ... While Seattle does not receive as much snow on average as many parts of the country, snowfall is not uncommon and can be heavy.

Australia is finally getting rain — but it's likely not enough to extinguish the fires devastating the country and might result in its own extreme weather. Firefighters have welcomed the rain in areas like Victoria and New South Wales, where they say it is helping to weaken fires.

If so, you are a part of a special tribe of people known as pluviophiles. By definition, pluviophiles are people who love the rain. You are probably used to listening to others whine endlessly about being wet and cold.
