More Tropical Weather heading our way

This shoud be interesting , as it will be interesting to see whether the storm moves to the south and then comes ashore from the west side, or perhaps will move in between our BI Eastern side.

Does the Sun Trigger Large Earthquakes?
http://www.suspicious0bservers.org/sun-t...rthquakes/

August 3, 2014 – Columbus, OH) KAHB LLC announces the discovery of a potential method for predicting the largest (+M8) earthquakes, using polar magnetic fields of the sun.

Using more than 35 years of data from the Wilcox Solar Observatory at Stanford University and from the United States Geological Survey, a model was constructed using patterns discerned in the polar magnetic fields of the sun. These patterns in solar magnetism were informally observed to match with the occurrence of large earthquakes on our planet, so mathematical modeling was used to formally develop an algorithm describing those relationships.

Dr. Christopher Holloman’s team of researchers at The Ohio State University Statistical Consulting Service was able to construct model that exhibited very strong agreement between solar magnetism patterns and the occurrence of large earthquakes. Formal testing of the model can only be performed by examining its performance over the next few years, but the agreement was sufficient to suggest that a relationship likely exists between solar polar fields, or magnetic fields associated with the north and south poles of the sun, and large earthquakes.

“The strong agreement of the model was surprising to everyone involved,” says Ben Davidson of KAHB, “but we have to understand the limitations of the analysis at this stage.” According to Davidson, this model is not predictive at this time; the analysis relies on data from the Wilcox Solar Observatory which requires at least 10 days to update past real-time, and is usually updated monthly. “The data is averaged in 10-day periods, so when a large earthquake happens, we still need to perform a retrospective analysis. What we have now is a rubric for gauging the correlations between these events into the future.”

“The most striking aspect of the model is that it is, for the most part, relatively simple,” says Dr. Holloman. “The patterns observed in the solar magnetic fields aren’t the result of applying some obscure mathematical functions. The algorithm is based on things like peaks and troughs in solar cycles or the absolute strength of one of the poles at a particular time. Such simple models are more often predictive than more complex models, and we are eager to see how the predictions play out over the next few years.”

In this retrospective analysis, the null hypothesis was that there was no relationship between the solar polar fields and M8+ earthquakes. Under this hypothesis, the fraction of days identified as residing in windows with increased likelihood of seismicity, as a percentage of the total days over the 35 years, would include a similar percentage of the large earthquakes over that same period. The analysis showed 41.6% of the days residing in these windows captured just under 78.8% of the M8+ earthquakes. “We cannot formally invalidate the null hypothesis, but the performance of the developed model is extremely encouraging. We believe it is likely to be validated by future data.”

As interesting as predicting large earthquakes would be, the lone prospective aspect of the model thus far involves periods of time when +M8 earthquakes are less likely to occur. These periods tend to occur following magnetic reversal of the solar fields at the sunspot peak of the ~11-year cycle of the sun, and could have significant implications for civil engineering projects near earthquake zones, mining, drilling, and other applications for which it may be advantageous to know when earth is less-likely to have a large earthquake.

Dr. Kongpop U-yen states that this analysis “suggests that their [M8+ earthquakes] major trigger mechanisms are external to the Earth. This may be linked to the electrical connections between the Earth and the Sun. Many seismologists have detected the fluctuation in electric fields in the Earth’s crust associated with earthquakes. Such an idea can be extended beyond the Earth’s crust toward the ionosphere and Van Allen radiation belts as they all move along together. NASA scientists also hypothesize that there are giant electric fields that power the Van Allen radiation belts, and have suggested that the Sun is the major contributor.” The connection is no longer limited to the surrounding space or Earth’s atmosphere, but to the penetration toward the Earth’s core as well. “After looking at the complete data set, it is not difficult for anyone to see that there is a connection. To be sure we did not fool ourselves, we back it up this finding using verifiable statistical analysis.”

Earth’s magnetosphere has been weakening since the 1600s, and Dr. U-yen is curious about the recent results from the ESA’s SWARM mission having a role to play in these earthquake correlations; “recently Earth’s magnetic fields are weakening more rapidly than in the past, making us more susceptible to space weather than ever before.”

The group is preparing a manuscript for submission based on the results of the study, which they hope will be accepted for publication shortly thereafter. Commenting further on the simplicity of the algorithm, Davidson notes, “We look at peaks in polar force and reversal of polarity – it really is that simple.”

Dr. Holloman is Director of the Statistical Consulting Service (SCS). The SCS is a team of faculty, staff, and graduate students in the Department of Statistics at The Ohio State University. Their mission is to provide professional statistical consulting support to OSU researchers and external clients in business, science, industry, and government. The SCS provides support in the areas of research planning; design of experiments; database development; survey design, administration, and analysis; statistical process control; and statistical modeling and analysis. http://www.scs.osu.edu

Another thing to look at is the Surface Sea Temps, as water above 26C begins to feed tropical cyclonic (ie hurricanes & such) storms, and in late july, that water temp was at our SE shores... but the biggest de-constructor for this storms is wind shear from storm fronts, and we currently have a front descending toward the main Hawaiian Island

Many folk truly believe that our mountains will protect us from storms, but a truly wise man I knew pointed out all of the islands with tall mountains that get hit with hurricanes and typhoons... most of the reason we do not get hit is that we are bordered on the east by very cool water, this helps reign in the cyclonic storms. NWest of our island there is a area of storm front development that can "shear" off the energy of the tropical cyclonic storms...granted there is a little mountain effect, but the tops of our mountains are so far below the tops of the cyclonic storms (the wide branching arc in the secondary circulation often reaching beyond 10km and the power generating core -"hot tower" in the 15km range, our Mauna Kea at 4.2km is more of a speed bump that a true storm blocker.. )

Note: if you do believe the ICC predictions for warming of tour eastern Pac waters, you may also start to realize as the eastern Pac warms, both factors that are currently working to limit tropical storms in the Hawaiian Islands may no longer be in effect....and we may get more cyclonic storms, and the ones we get will have more warm water fueling them...

If what they say about the oceans warming up..turns out true..Hawaii in the future will be an interesting place to live.

Thank you Carey for providing discussion of the factors involved in hurricane development and site specific information for our tiny island community. I have often questioned peoples' insistence that the mountains protect us with their height but your reference to water temperatures, particularly on the windward side can either diminish or promote hurricane strength nearing our islands. It just makes sense that strong trade winds would bring cooler northern waters to our eastern shores and long term lack thereof would promote warmer waters. It seems to me that in the past few years we have had a lot more turbidity in the 10-15 degree latitudes but that this year that band seems to be pushed northward into our island waters.

The discussion of hot towers is fascinating and provides insight as to just how many factors are involved in driving our weather and how scientific information is adapted and refined over time as our understanding grows.

After we get through this storm there is another tropical storm following the same relative path by a couple of days which seems to be shaping up to be another hurricane. I guess we will all find out soon enough...

Carey - thank you for your post. Ask any qualified meteorologist about the effect Mauna Kea and Mauna Loa have on hurricanes will basically say the same thing you have. It's a myth that they deflect hurricanes away from the island. Right now, and I will admit this is just a gut feeling and not based on anything scientific at all, I'm a little more concerned about that second system, currently named Ten-e. It's still a long way from us though, so a lot can happen. The track for Iselle has been quite consistent for a while now apart from some small shifts north and south (and some uncertainties about its westward acceleration in a few days), so think it'll likely pass through the islands, but not as a hurricane.

Also wondering why there is a long post on earthquakes in this thread and how an earth it's related to hurricanes.

Check out Iselle 5 AM report this morning.

Iselle upgraded to category 4 which was unexpected by some of the models (I think there are 5 or 7 of them).

And Julio is right behind Iselle.

there is a reason why most of the Cyclones/Hurricanes fade away to windy rain...

from wiki

A Hawaiian hurricane is a tropical cyclone that forms in the Pacific Ocean and affects the Hawaiian Islands. Hawaii lies in the central Pacific, where about four or five tropical cyclones appear each year, although as many as eleven have occurred, such as in the 1992 and 1994 seasons; rarely do these storms actually affect Hawaii.

Hawaii's apparent immunity to most hurricanes
Hurricanes in the Central Pacific (140° W to 180 ° W) generally travel from east to west, however, some including Hurricanes Iwa (1982) and Iniki (1992) track in a northerly direction

The islands of Hawaii, with Kauai as the notable exception, appear to be remarkably immune from direct hurricane hits. The USGS states that "more commonly, near-misses that generate large swell and moderately high winds causing varying degrees of damage are the hallmark of hurricanes passing close to the islands."[30] This has also drawn media attention.[31][32]

One notion is that Hawaii’s volcanic peaks slow down or divert storms.[33] A partial source of this idea may be the long list of hurricanes in the above paragraphs that dissipated into tropical storms or depressions upon approaching the islands. Satellite images of hurricane Flossie's breakup when approaching Hawaii Island fueled this idea.[34] Another example may be hurricane Felicia which dropped from Category 4 down to a tropical depression with residual winds predicted at only 35 miles per hour (56 km/h).[35]

Tropical Storm Flossie (no relation to Hurricane Flossie in 2007) provides still another example. On July 28, 2013, the storm appeared headed for a direct hit to the Big Island, home to Mauna Kea and Mauna Loa. Both mountains rise to elevations in excess of 13,000 feet above sea level, and as Flossie approached the island, its track shifted abruptly overnight and assumed a more northerly alignment, heading instead to the island of Maui on July 29.[36]

Wind data in particular supports the USGS assertion that hurricane damage has been low on all islands except for Kauai. Data collected by the Western Regional Climate Center show no hurricane-strength winds on any Hawaii Islands with the exception of Kauai.[37] Despite this data, FEMA classified all of Hawaii as being in a "Wind-Borne Debris Region".[38][39][40]

Yet we are REQUIRED to have hurricane insurance if we have a mortgage, for homes in an area that has NEVER been hit by an actual hurricane during recorded history. What a load of crap.

Justin, we had the same reaction when we bought our house, and my then 82 yr old MIL put it this way...."looks like none of the houses here have had a fire....but you are getting fire insurance!" Of course I know it IS more likely to have a fire than a hurricane in most areas...but she was right, our neighborhood has not had a major fire...

Looking at the damage in areas that have been hit with hurricane force winds, I guess I am going with the "it is better to have it and never need it, than to not have it and need it" philosophy!
