This happens when the normal winds weaken which allows the warm water that is usually found in the western Pacific change direction and instead move towards the east. This warm water replaces the cold water which is normally found near the surface of the eastern Pacific. All these occurrences are what affects a lot of weather patterns in many parts of the
From august 29th to august 30th hurricane Katrina made landfall and along with land fall lost its fuel source. When Katrina hit wind speed decreased with air pressure started to rise, warm water was cut off from the hurricane as its fuel source the hurricane slowly fizzles
Hurricanes need the ocean’s water temperature to be about 80 degrees to a depth of about 150 feet. Another factor of the forming of hurricanes is the rapid cooling of the warm water vapors that were evaporated, which causes condensation (the second step of the water cycle). The third step of the water cycle is precipitation and that happens when too many water vapors are condensed and rain starts to fall. Humidity is also needed in the
An example of this can be found in glaciation. During glaciations the weight of ice pushing on the Earth can depress the crust, causing the land to fall relative to the level of the sea. When the ice goes in warmer periods the land rebounds upwards as Scotland and Northern Britain are today - rising relative to the level of the sea. Eustatic sea level change is a GLOBAL change in sea level, linked directly to the temperature of the Earth. In warmer periods there is less ice and the water is warmer, so expands and sea levels rise.
Global warming has been a giant issue in our world today the rising of seas, melting of ice caps, experiencing some of the worst natural disasters in centuries. We have known of this since 1980 to be exact. I've just got done reading two really good articles on global warming. Two articles that I read were Greenland Ice Cores: Frozen in time and the other article is named the Rising Seas . These two articles really informed me on whats happening in the world due to global warming.
Not just one area but globally! That would give us a better indication of global warming. Artic sea ice is another thing we should be monitoring. “September Arctic sea ice is now declining at a rate of 11.5 percent per decade, relative to the 1979 to 2000 average” (Global Climate Change: Key Indicators, 2014). Due to, again warmer temperatures both maximum and minimum we are seeing ice melt.
Since air is less dense than water wind can only remove fine sediment such as silt, sand, and clay, but unlike running water, wind is not confined to channels. It can have a widespread effect over vast areas, and the faster the wind blows, the more sediment it can move. Wind action in dry climates can result in thick, choking dust storms. Air pressure differences cause wind as air warms and cools and changes density. The extreme temperature fluctuations that can occur in dry climates causes winds to become stronger.
Throughout and after an ice age, eustatic change takes place. At the start of an ice age, the temperature falls and water is frozen and stored in glaciers inland, suspending the hydrological cycle. This results in water being taken out of the sea but not being put back in leading to an overall fall in sea level. Conversely, as an ice age ends, the temperature begins to rise and so the water stored in the glaciers will renter the hydrological cycle and the sea will be replenished, increasing the sea levels. Increases in temperature outside of an ice age will also affect the sea level
ABSTRACT Global warming causes many changes in weather patterns including greater temperature variability and more extreme temperatures. In this study we examined the damage and recovery in Aesculus glabra (Ohio buckeye) in Trelease Woods after a late frost in the spring of 2007, potentially caused by global warming. 1) If temperature and wind gradients directly affect the pattern of damage and recovery of Ohio buckeye, then as the distance of Ohio buckeye from the forest edge increases the percent leaf damage done by frost will decrease. 2) If the total leaf area available for photosynthesis in an Ohio buckeye directly affects its recovery from frost damage, then as percent leaf damage increases, recovery (based on percent canopy fullness,
Perth’s climate also assists the issue of photochemical smog as plenty of sunlight with moderate winds and high temperatures arise. Morning peak hour pollution is blown out to sea by north easterly winds. If is then warm enough the chemical reaction mentioned above occurs to produce photochemical smog, the Fremantle doctor (strong westerly) then returns it over the city. The Darling Range and Fremantle doctor acting as barriers along with high pressure systems that bring masses of UV and Perth’s high car usage result in the city being a photochemical smog hotspot. Another form of atmospheric pollution that occurs in Perth is Haze.
