Snow flurries April 5 2021.jpg

April snow. Well, the snow won't really settle, but the weather will stay chilly for the next ten days, meteorologists say.

Cyclone Tauktae Strikes India
Earth Observatory, May 17, 2021
Story by Adam Voiland.

<<An unusually powerful tropical cyclone named Tauktae struck the Indian state of Gujarat on May 17, 2021. The Visible Infrared Imaging Radiometer Suite (VIIRS) on the NASA-NOAA Suomi NPP satellite acquired this natural-color image of the storm a few hours before it made landfall between Porbandar and Mahuva.

As Tauktae approached land, the U.S. Joint Typhoon Warning Center reported maximum sustained winds of 100 knots (185 kilometers) and gusts up to 125 knots (230 kilometers), equivalent to a category 3 or 4 hurricane. That made Tauktae the fifth-strongest storm observed in the Arabian Sea since 1998. Winds of that strength can easily snap trees, topple power lines, and damage homes. The storm also pushed a destructive storm surge of water onto the Indian coast; reports suggest it may have been as high as 3 meters in some areas.

Even before making landfall, Tauktae caused a trail of destruction in Kerala, Karnataka, Goa, and Maharashtra as it brushed India’s northwest coast over the weekend. According to news reports, the storm contributed to the deaths of at least 12 people, destroyed hundreds of homes, and caused power outages and traffic jams. More than 150,000 people evacuated Gujarat in anticipation of Tauktae’s arrival.

The North Indian Ocean generates only about 7 percent of the world’s tropical cyclones, but storms can be quite devastating when they occur because of the large number of people who live along low-lying coastlines. Compared to the Bengal Sea to the east, cyclones are uncommon in the Arabian Sea, an area that typically sees one or two storms per year. Cool water temperatures, dry air, and unfavorable upper-level winds typically make storms in the Arabian Sea weak and short-lived, though powerful storms occasionally come together under the right environmental conditions.

In Tauktae’s case, conditions were ideal. Upper-level winds were calm and conducive to storm formation. Sea surface temperatures in the Arabian Sea were about 31° Celsius (88° Fahrenheit) as the storm approached Gujarat, a few degrees warmer than usual for mid-May. A rule of thumb among scientists is that ocean temperatures should be above 27° C to sustain a tropical cyclone. During the past few decades, a group of NOAA researchers have observed an increase in the intensity of tropical cyclones in the Arabian Sea, particularly in the post-monsoon season. The group’s modeling results indicate that global warming and rising ocean temperatures are among the reasons for the change.>>

I obsereved triple rainbow recently - what an amazing spectacle! Unfortunatelly my phone had low battery and I wasn't able to take picture and I was just standing and enjoying that view! This year it rains much more often, that is why I see rainbows almost everyday :)

It's been nothing but hot, hot, hot, lately! It's supposed to rain to day; but the radar says we will probably be missed! So probably no rainbows! :( On the bright side it will be cooler! I have seen a few triple rainbows over the years; they get pretty light by the time they get to be #3! :wink:

I don't normally complain about the heat, but we are experiencing very hot weather right now. Ridiculously hot you might even say. I think I just saw two people walking down the street wearing stillsuits.

Ha! I haven't seen that episode but there are indeed "hip donut" places in P-town.

Which reminds me - have you heard about the hipster who burned himself on his soup? He ate it before it was cool.

Floods in the eastern US, drought in the west. :ohno: As water resources dwindle in the west and excess water accumulates in the southeast, will it ever become feasible to construct a sea level water transportation pipeline?

A National Aqueduct System may seem far-fetched but as resources become more stretched, it may eventually become necessary. :|

  • Dirty floodwater from (some) eastern floodplains (at sometimes) is cheap.
    Regular clean fresh water from eastern reservoirs may be a little trickier situation.

A minimum energy consumption for seawater desalination of around 1 kWh/m3 has been determined, excluding prefiltering and intake/outfall pumping. Under 2 kWh/m3 has been achieved with reverse osmosis membrane technology, leaving limited scope for further energy reductions as the reverse osmosis energy consumption in the 1970s was 16 kWh/m3.>>

Very good point. Pumped water does have some benefits if the power used is renewable but clean water is preferable.

A large solar array for both power & desalination makes a lot of sense for southern California so as to take the pressure off of the Boulder Dam. Only then might one be able to make the case for sharing some of the East's fresh water supply(; a technical & political dilemma).

Had ourselves a nice little snowfall this afternoon. It only stuck up on the higher hillsides, as the temperatures weren't too cold. Very pretty with the still changing aspens, though.
