ATMOSPHERIC RIVERS -
bringing us new weather? Atmospheric river is bringing huge amounts
of tropical moisture to California,
prompting weather forecasters to issue alerts for high risks of flooding.
--------- 3816 - ATMOSPHERIC RIVERS - bringing us new weather?
- Atmospheric rivers are channels that
form in Earth's atmosphere and funnel water vapor from the typically humid
tropical regions to drier areas farther away from the equator. These channels
can transport huge amounts of water within a short period of time, causing
deluges when they make landfall.
-
- The type of atmospheric river
threatening California on January 4th and 5th, 2023 is a
phenomenon that appears regularly. It's sometimes called the Pineapple Express,
a reference to the fruit commonly grown in Hawai'i where this river originates.
-
- The current atmospheric river has
combined with a region of low air pressure that swirls above the Pacific Ocean,
together forming a powerful storm that threatens the usually sunny state.
-
- Satellites of the U.S. National Oceanic
and Atmospheric Administration (NOAA) are monitoring the weather system,
revealing its various aspects including wind speeds and expected amount of
rain.
-
- In higher altitude regions, such as in
the Sierra Nevada Mountains, the rain will turn into heavy snow.
-
- This is not the first atmospheric river
to hit California recently. On the last
day of December, a similar channel dumped a record-breaking 5.46 inches of rain
on downtown San Francisco.
-
- The current storm system threatens to
pour over 1 inch per hour on the already soaked ground, causing concerns that
mudslides. Over 11.6 inches of rain fell in San Francisco in
December,2022. That's more than twice the December average for the city, which
is 4.76 inches.
-
- Scientists reaffirm the disastrous
consequences that climate change’s effects will continue to have. They show
that as the globe continues to warm, weather patterns are becoming more severe,
the seas more unruly and disasters more unpredictable.
-
- These effects are even visible to
Earth-observing satellites, watching from space. Satellites see climate
change's impact in the form of wildfires, melting ice, shifts in the seasons,
growing floods and much more.
- Of course climate changes. That is what climate is. There are many cycles that can be shown to
have occurred over thousands of years.
