In simple terms, the windward side of the island is where most precipitation takes place and the leeward side is the drier side of the island. Kauai is positioned in the track of the east-northeasterly trade winds, thus producing wakes in the lee. The leeside of Kauai seems to be of major interest in terms of studies of the wakes. Evidence of Kauai’s trade winds largely contributes to Kauai’s weather patterns. Particularly, weather patterns and environmental observations have geologically changed the wake of Kauai. Observations of the wake of Kauai have been of interests in geological studies because of changing factors connected to wind flow in terms of trade winds, erosion, changes in island temperature, cloud trails, and island-scale circulations in relation to both the leeward and windward sides of Kauai. Trade wind flow is heightened around the Kauai Island. Kauai itself stands within “…the path of the east-northeasterly trade winds, creating wakes in the lee” (Yang, Ma, & Xie, 2007). The development of sea breezes turns the winds into westerlies …show more content…
Thusly, chronic coastal erosion is beginning to become a huge problem along a majority of the U.S. coast, exclusively on Hawaiian Islands (Romine and Fletcher, 2013). “Kona” storms, with southerly winds and waves, can trigger momentary erosional events to south and west exposed beaches on the coast (Romine and Fletcher, 2013). Erosional events are undoubtedly proving to control most shoreline changes throughout the state Hawaii, let alone Kauai. Romine and Fletcher’s studies of historical shorelines on major Hawaiian Islands, including Kauai, have proven that shoreline changes on the islands are displaying a dominant trend of being caused by erosion (2013) on the leeward and windward sides of the …show more content…
The trail cloud band develops around noon and peaks in cloudiness in the early afternoon. The analysis of numerical simulations of the Kauai wake suggests that a dynamically induced convergence zone forms in the lee of Kauai. Images have distinctly shown “excessive cloudiness and a peak in trail clouds” that are most likely a result of island thermal forcing, and additionally displays an escalation in cloudiness over the Kauai wake, which yet again verifies the “importance of diurnal variation of island heating/cooling” and island thermal forcing (Yang, Xie, & Hafner, 2007). Additionally, trade winds that come and travel across from the northeast carry moisture-laden clouds that instigate high chances of precipitation, which yet again inflicts changes on the windward and leeward sides on the wake of

In the future, scientists predict that Yellowstone will erupt very violently, leaving the United States covered in inches of ash. While scientists think this will not happen for another 1 to 2 million years it could happen at any minute (Cimons). While, Hawaii's future is already beginning to unravel with a new island forming called Loihi. This new island is forming to the south of the island of Hawaii 3,000 feet below the surface of the Pacific Ocean. There is a large and fierce

The more coastal erosion there is, the higher the chance is for saltwater contaminating freshwater resources and the salt from the ocean can cause soil to be uninhabitable to plants (Again this can affect agriculture). Coastal erosion is not only an issue for water resources, it’s also a direct issue for the communities. The communities on islands lay very close to the coast and important infrastructures are one of them. Islands cannot get all of their resources from the local farmers, so they import it via plane or boat. The problem with that is the airports and ports are all on the coast. Coastal erosion has the power to ruin airport runways and docks of the harbors and ports; this means that eventually communities will be starved of basic necessities and there will be no way of getting in basic needs. Not only will airports be ruined, so will our tourism industry. Coastal erosion will eventually ruin the beaches that attract tourists. Island communities depend on the tourism industry because that industry brings in a lot of money every year. Without tourists, communities will struggle financially. Lastly, the ecosystem of the islands will suffer the
The Earth has been experiencing a considerable amount of climate change for the last several decades. Natural factors that contribute to the climate system consist of: solar output, volcanic activity and earth’s orbit around the sun. The two factors relevant on timescales of contemporary climate exist in volcanic activity and changes in solar radiation. The earth’s energy balance primarily influences the amount of incoming energy from volcanic eruptions, which have a relatively short-term effect on climate. Changes in solar output have contributed greatly to climate trends over the past century. The effect of greenhouse gases in the atmosphere has been at least ten times that of changes in the Sun’s output and the ocean covers more than 70 percent of the earth’s surface, receiving twice the amount of earth’s radiation. Although the sun is the engine that drives all the weather, oceans and atmosphere control the sun 's energy along certain
Despite the intense efforts to uncover information on the prehistoric Native Americans occupying the Washington Coast, very little archaeological evidence has been uncovered to suggest prehistoric occupation (Cole, et.al, 1996). A finding that fiercely contrasts with the early historic record, which projects a population total of 6,000, and as such, should demonstrate heavy if not consistent findings within the region (Cole, et.al, 1996). However, this is not the case for the Washington State coastline. Despite the extent of research that has been conducted from 1976-1994, the archeological findings along the Southern Washington Coastline are nonexistent, less for what has been found upon the surface. Cole and associates attempted to find the missing link between as to where the evidence may have gone. In 1990 two geologist accidentally uncovered prehistoric fishing camps in the interdial zone, covered by mud from an earthquake that occurred 300 years ago (Cole, et.al, 1996). By studying the geophysical qualities of Southern Washington (1700 AD), Cole and associates, discover that seismic activity at the Cascadia subduction zone caused not only an earthquake, but a substantial Tsunami, which worked to bury the
According to the National Oceanic and Atmospheric Administration, almost 40% of the population lives in high population-dense coastal areas. Around the world, eight of the world’s ten largest cities are situated near a coast, with about 250 million people living by a coast line less than 5 feet above sea level. It is projected that all of these people will be directly affected in some way by seawater rising in the future (Siegert, 2017). For the county of Orleans Parish, the rapid loss of coastal land is not a future scenario, but a current reality. Due to our unique geography, Louisiana loses about 16 square miles a year; the rapid erosion of Louisiana’s cost is only expected to accelerate over time. (Wernick, 2014).
For our project, we decided to do the Punaluu Black Sand Beach. Punaluu is on the main island of Hawaii. Punaluu Black sand beaches started to form over hundreds or thousands of years. On Hawaii, there is a hot spot underneath it. There is a non-explosive volcano that spills out lava over thousands of years with hundreds of small eruptions each day. A cliff of black igneous rock formed where the lava meets the ocean. Then over many hundred of years, it is slowly eroded away by the big and small waves. When the waves start to erode away the rock on the cliff, it washes rock fragments and basalt onto the beach.
Wind powered surface currents and waves, along with moon and sun powered tides, greatly impact Earth’s coastlines. As warm or cold water ocean currents affect coastal climates, waves release energy, shifting sand and sediments, eroding and replenishing coastline shores; all while tides raise and lower sea level. Florida’s east coast, encompassed by barrier islands, is affected by subtropical ocean waters provided by the Gulf Stream, facilitating warm and humid climates, as well as hurricanes. As these warm ocean waters interact with Florida’s barrier islands, through wave action and tides, its coastline continuously transforms.
This paper is going to be about how caostal erosion is doubling on the coasts of Hawaii. Because of global warming the oceans sea levels are rising and causing erosion on the coast’s. How would you feel if the foundation of your house was slowly getting eroded by the sandy beaches and slowly crumbling.
According to the Encyclopedia Britannica, American Samoa’s climate is warm and tropical with nice trade winds. This will support my open market business because, having rain or too much wind wouldn’t attract people but having nice weather would keep the crops nice and bring more people to my business.

Climate change is causing many problems for not only Honolulu but the entire state of Hawaii. First and for most, temperatures are increasing which is causing negative effects such as rising sea levels, tropical storm and coastal flooding. Moreover, it is limiting the quality and quantity of fresh water, reducing the growth of coral and stressing native pacific plants and animal, which may in fact result to migration and extinction. Due to the threats to the people of Hawaii's basic needs and public health and safety, some locals are deciding to immigrate to another state since Hawaii alone is exposed to heat related illnesses and is dependent mainly on imported goods. Climate change may drastically affect Hawaii and the many cities in it
If conditions remain favorable, the depression may develop further into a tropical storm and, later, into a full-blown hurricane.” (Genesis, 99). On page 34 of the book, Sudden Sea, the author describes a discovery in the Sahara Desert. Meteorologists noticed a slight shift in the wind; an area of unstable air was passing over northwest Africa. Within a day or two it moved over the Atlantic Ocean to around the Cape Verde Islands. This should have been the first sign to the Weather Bureau to watch this particular storm. Although storms born off of the Sahara Desert were more likely to become nothing, there was still a slight chance it would develop from the unstable air combining with moisture built up from the heat of the equator off of the islands.
Summary: The authors compare 2004-2013 TCs in the North Atlantic and East Pacific basins, using IKE (TC extended best track data set) and rainfall (TRMM-3B42). The introduction defines the concept of IKE and explains that a comparison of IKE in the EP and AL basins will be carried. The following analysis provides the seasonal cycle of IKE and TC count, then shifts the focus to:
