Hawaii’s MountainsHere’s a link to the live web cam on the summit of near 13,800 foot Mauna Kea on the Big Island of Hawaii. This web cam is available during the daylight hours here in the islands…and when there’s a big moon shining down during the night at times. Plus, during the nights you will be able to see stars, and the sunrise and sunset too… depending upon weather conditions.



Aloha Paragraphs

A low pressure system is moving away towards the far
northeast…with its trailing cold front between Maui
and the Big Island of Hawaii


http://www.goes.noaa.gov/GIFS/HAIR.JPG
Frontal cloud band is keeping the islands partly to mostly cloudy…
from Maui County to the Big Island – high cirrus clouds south

Showers are falling over the islands locally…mostly over
parts of Maui County and Oahu at the time of this writing


Here’s the looping radar image for the
Hawaiian Islands


High Surf Advisory…rough surf conditions along north and east shores 

Small Craft Advisory…rough surf and stronger trade winds over
all coastal and channel waters

Gale Watch…for possible winds of 39 to 54 mph this evening
through late Wednesday night 


~~~ Hawaii Weather Narrative

Winds generally from the northeast
…as a cold front stalls over the eastern islands. Here’s the latest weather map, showing the Hawaiian Islands, and the rest of the North Pacific Ocean, along with a real-time wind profiler of the central Pacific. We find high pressure systems located to the north and northeast of the state, with associated ridges of high pressure both north and northeast of the state. As a result of these high pressure features, and a low pressure center located far to our northeast, with its trailing cold front dissipating over the eastern islands, our winds will come in from the northeast. These classic trade winds will be strong and gusty into Tuesday…likely picking up another notch in strength by mid-week. The long range outlook shows no definite end to this trade wind episode.

Showers will continue along the windward sides…as a cold front falls apart between Maui and the Big Island. We’ll continue to be wet along our windward sides, especially in Maui County and the Big Island, as this dissipating cold front contributes its moisture into our trade wind flow. As the trade winds rebound fully in the wake of the front, the windward sides will see shower activity continuing for several more days…if not through the rest of this work week. The leeward sides in contrast, will turn drier with more favorably inclined weather conditions later Tuesday onwards. I’ll be back with more updates on all of the above, I hope you have a great Monday night wherever you’re spending it! Aloha for now…Glenn.

How Desalination Technology Is Helping Solve California’s Drought  Four years of devastating droughts in California have pushed cities and counties in the Golden State to seriously consider turning to the one drinking source that is not depleting anytime soon – seawater. With the Pacific Ocean abutting their shores, water desalination may be the much-needed solution for Californians. But desalination has its disadvantages, the chief ones being the high costs and the potential environmental damage.


To address these challenges, California is turning to the world leader in cutting edge desalination technology – Israel. A $1 billion desalination project is already underway in San Diego County – which will be the largest seawater desalination plant in the Western Hemisphere – and Israeli engineers have been called in for their expertise.


Currently under construction in Carlsbad, 35 miles north of San Diego, the plant could potentially provide Californians with 54 million gallons of water a day. The plant is using technology Israelis have been using for years, reverse-osmosis, which involves forcing seawater through a film with tiny holes that allow only water molecules to pass through, while the larger salt molecules cannot.


2014 was California’s third driest year in 119 years and according to the US Geological Survey; it was also the warmest year in recorded history, leading California to declare a drought state of emergency last year. Earlier this month, another frightening figure was published: The California Department of Water Resources measured the statewide water content of Sierra snowpack (which provides about one-third of the water used by California’s cities and farms) at 5 percent, the lowest level since 1950. In response, the governor recently announced mandatory State-wide water cutbacks.


Despite this, the Golden State has only a handful of small desalination plants. But with the help of Israel Desalination Enterprises (IDE Technologies), the $1 billion desalination plant San Diego is due to become reality next year. According to IDE – which is also working on desalination projects in China, India and Australia – the Carlsbad project is a “complete game changer for desalination in the US.” This project is expected to provide clean water to 300,000 people and generate roughly $50 million annually for the regional economy. “The plant overcame significant practical, regulatory and economic hurdles to deliver a cost-effective and environmentally friendly water supply,” IDE said.


Critics of the reverse-osmosis technology have claimed that it is too costly and requires too much energy, making it environmentally damaging. But IDE Technologies says its production costs are among the world’s lowest and that it can provide an average family’s water needs for roughly $300-$500 a year. Israel’s largest desalination plant, for example, sells desalinated water to the Israeli government for about 60 cents per cubic meter, which is lower than traditional water purification methods. Using highly efficient pumps, the plant also consumes less energy than similar desalination stations around the globe.


Israel, a land that is two-thirds arid, has long been forced to come up with creative ways to conserve, recycle and desalinate water. The country has become a leader in the field of water preservation, coming up with industry-changing technologies such as drip irrigation in 1964. In fact, the serious attention Israel has paid to its water supplied means that the country now has a water surplus – a first in its history. About 40 percent of Israel’s tap water is desalinated sea water – a figure expected to reach 50 percent by 2016 – and so is a large part of the water for agriculture.


And with an estimated 1.8 billion people around the globe who don’t have adequate access to clean water, desalination technologies developed in Israel are in high demand.
