What Is The "Pineapple Express" Phenomena:

Meaning:

California and other regions of the West Coast have experienced a string of atmospheric rivers over the past two weeks. The "real Pineapple Express," a particular instance of a frequent weather phenomena that resembles a conveyor belt collecting precipitation, is claimed to be the origin of the rain that will begin falling in California on Wednesday, according to forecasters.
Weather experts refer to these long, narrow sections of the atmosphere as atmospheric rivers because they convey the majority of the water vapor outside the tropics and have been wreaking havoc on California and other parts of the West Coast for the past two weeks.
 
According to the National Oceanic and Atmospheric Administration, they were "like rivers in the sky.
 

“Is The "Pineapple Express" A Typical Occurrence?

What Is The
Although they can happen everywhere, including the eastern United States, where they frequently carry moisture from the Caribbean, these rivers in the sky are most common along the West Coast. Additionally, they carry a lot of moisture, perhaps even more than the normal flow of the Mississippi River at its point of entry into the Gulf of Mexico. This fluid might turn into rain or snow when it comes into contact with the ground. Because these atmospheric rivers supply a constant flow of moisture, precipitation is frequently copious, as has been the case recently in California.
 
Location is important for an atmospheric river to be a "genuine Pineapple Express," even if they exist in a variety of sizes and shapes. It must begin close to Hawaii for the moisture to be drawn into the atmosphere towards the tail end. The river must then continue to flow through the atmosphere all the way to the American West Coast. 
 

What Results From This?

The end outcome is something akin to a conveyor belt for precipitation, regardless of whether an atmospheric river is a ‘Pineapple Express’ or not. As a result, they are crucial to the survival of coastal states, whose water supply is greatly dependent on precipitation: According to the NOAA, just a few atmospheric river events account for between 30% and 50% of the yearly precipitation on the West Coast. However, when the rivers are exceptionally powerful or form what are known as "atmospheric river families," the results can be disastrous, as is the case with the current widespread flooding in California.
