Atmospheric circulation

et al., 2008). Black carbon is naturally occurring but a large portion of atmospheric BC is the anthropogenic and transported to Alert by circulation systems which bring BC along with other aerosols from many other locations. Alert is primarily influenced by BC emissions from Siberia/ Europe during late winter and spring and regional sources in the summer (Sharma, Andrews, Barrie, Ogren, & Lavoué, 2006). These circulation patterns are created as wind vectors travel along mostly persistent…

Third, because there has been a significant temperature increase from the past ice age, we know that there has been a significant increase carbon dioxide. For example, when Crowley attempts to identify the correlation between temperature and inter-solar system phenomena, he emphasizes that "There is an unprecedented residual warming in the late 20th century that matches the warming predicted by GHG forcing. The temperature estimates for 2100 also exceed the most comprehensive estimates (50) of…

extent through the end of the century. Despite this anticipated trend, inter-annual variability in arctic sea ice extent remains relatively unpredictable. The variables affecting sea ice growth include, but are not limited to, large-scale atmospheric circulation, local meteorology, and dynamical surface fluxes, thus the forcing on arctic sea ice is complex issue. This study takes a closer look at the effect of wintertime downwelling longwave radiation on summer sea ice concentration,…

thunderstorms that originates over tropical or subtropical waters and has a closed low-level circulation” (“Tropical”). Hurricanes need many factors to help develop from a simple storm to a tropical storm and from a tropical storm to a hurricane. They need warm sea surface temperatures, low atmospheric winds, and a rotating area of air to form these storms (Gray, 1994). Hurricanes start when the atmospheric pressure is lower than the pressure around it. This change in pressure evaporates water…

Weather Disasters Weather disasters happen because weather conditions change, this brings unusual weather results, which can lead to the unexpected or demand emergency actions. Furthermore, these weather conditions can easily turn into weather disasters, which by history, can cause major damage in largely populated areas. Examples of such weather or climate changes come in forms of floods, volcanic eruptions, earthquakes or tsunamis, which can all cause disasters. With that in mind, disasters…

Tornadoes are one of Mother Nature’s most violent of all atmospheric forms. A tornado is a column of vertically spinning air originating from a cumulonimbus cloud that can contact the ground and cause catastrophic damage. The deadliest tornado in U.S. history to date is called the Tri-state Tornado. It occurred in 1925, sweeping through three states for three and a half hours. It killed 689 people and injured 2,000. After many hours of research I have found several interesting facts about…

What would happen if all of the marine life on Earth today were to go extinct? Would the loss affect humans at all? The answer to these questions, is yes, because the ocean provides 50% of our oxygen. Without saltwater animals, there would not be any underwater plants to provide this oxygen. Because humans are slowly destroying marine life, which is essential to all life on Earth, it is necessary to rescue, rehabilitate, and release marine animals. One of the main causes of death and…

factor that influences the data results is El Nino. What is El Nino? El Nino is "A southward-flowing, nutrient-poor current of flowing, nutrient-poor current of warm water off the coast of western South America, caused by a breakdown of trade-wind circulation."(Oceanography: An Invitation). Specifically, El Nino influences seawater temperature, density, and oxygen in the water. First all, El Nino influences seawater temperature by causing seawater temperature to increase. For example, in fall of…

Introduction and Social Relevance 2015 was a tragic year for South Australia. 102 people died on the roads and over 750 serious injuries occurred in South Australia alone. 44 of the fatalities were young men and women who died due to driving over the allowed alcohol consumption limit of 0.05 (Responsibility, 2016). This did not however need to be the case, these fatalities would not have occurred if the drivers were tested and stopped beforehand. Over 600 000 drink driving tests occurred last…
