Storms: You Will Create A Draft PowerPoint Presentation ✓ Solved

STORMS You will create a draft PowerPoint presentation

You will create a draft PowerPoint presentation relative to the final project that incorporates what you have learned about general circulation since the last milestone, as well as aspects of the Storms section by introducing one of the four principal types of storms: midlatitude cyclones. Your submission should be detailed from an atmospheric science perspective but also contain elements relative to damage, death, and ecosystem impacts. Be sure to include detailed speaker’s notes and appropriate graphs, charts, figures, pictures, or other relevant media to support your ideas on the following topics:

• Examine the general circulation of the (global) atmosphere (semi-permanent pressure cells, primary winds) and secondary circulations.
• Describe the life cycle of midlatitude cyclones (including how and why the systems develop, move, mature, and dissipate) and the resulting weather elements associated with them.
• Summarize the severe weather elements of midlatitude cyclones, including critical factors relative to damage, deaths, human safety, and ecosystem impacts.

The below topics should be represented in a slide and images where available.

• General Circulation: Three-Cell Model
• General Circulation: Semi permanent Pressure Cells
• General Circulation: Wind and Pressure
• General Circulation: Ocean–Atmosphere Interactions
• Storms: Life Cycle
• Storms: Severe Weather
• Storms: Causes
• Storms: Mitigate

Storm of The Century: Read Superstorm of 1993, “Storm of the Century.” In your post, compare that weather event to an “average” midlatitude cyclone traversing the same location. Why and how (meteorologically speaking) was this storm different from normal? Be sure to describe the initial meteorological conditions and results of this storm compared to an average storm. Could anything else have been done to prevent the devastation the 1993 storm created?

Paper For Above Instructions

This presentation aims to provide a comprehensive understanding of midlatitude cyclones, focusing on their life cycle, severe weather implications, and their relationship with global atmospheric circulation. Midlatitude cyclones are critical systems in the weather of temperate regions, producing diverse weather phenomena that can significantly affect ecosystems and human safety.

General Circulation of the Atmosphere

The general circulation of the atmosphere is governed by a combination of factors, including semi-permanent pressure cells and primary winds. The three-cell model describes the large-scale atmospheric circulation comprising the Hadley cell, Ferrel cell, and polar cell. Each cell plays a vital role in distributing heat from the equator toward the poles. The Hadley cell operates between the equator and about 30° latitude, where warm air rises, creating low pressure at the surface. As the air cools, it sinks at around 30° latitude, forming high-pressure zones (Corcoran & Hennon, 2022).

The Ferrel cell operates between 30° and 60° latitude, characterized by westerly winds. This cell is essential because it helps in the development of midlatitude cyclones. The polar cell extends from about 60° latitude to the poles, featuring cold air that creates high-pressure areas. Together, these cells influence secondary circulations such as trade winds, jet streams, and ocean-atmosphere interactions, which are crucial for understanding weather patterns and system development (Peixoto & Oort, 1992).

Life Cycle of Midlatitude Cyclones

Midlatitude cyclones undergo a distinct life cycle encompassing several stages: genesis, maturation, and occlusion. They typically develop at the polar front, where warm air from the south meets cold air from the north. This convergence causes the warm air to rise, leading to low pressure. The cyclone's initial formation is often triggered by upper-level disturbances in the atmosphere (Davis, 2010).

As the cyclone matures, it can produce various weather phenomena, including heavy precipitation, thunderstorms, and strong winds. The cyclone will peak when warm and cold fronts are well-defined, leading to impactful weather. Eventually, the system occludes as the cold front catches up with the warm front, resulting in a decline in the cyclone's intensity and eventual dissipation (Baker, 2017).

Severe Weather Elements

Midlatitude cyclones can produce severe weather, including blizzards, heavy rain, and tornadoes. These weather systems are responsible for significant damage, including infrastructure collapse, loss of life, and disruptions to ecosystems. For instance, strong winds and heavy snow associated with cyclones can cause power outages and hazardous travel conditions (Smith & Smith, 2021).

The human safety component is critical, as cyclones can lead to injuries or fatalities during extreme weather events. Preparedness and awareness can mitigate damage, as can timely alerts and weather forecasting. Understanding the impacts on ecosystems is equally important, as these storms can lead to soil erosion, flooding, and ecosystem shifts (Muller & Chan, 2020).

Comparative Analysis: Superstorm of 1993 vs. Average Midlatitude Cyclone

The Superstorm of 1993, also known as the “Storm of the Century,” was an extraordinary meteorological event, greatly different from an average midlatitude cyclone. Initial conditions included a deep trough in the jet stream, which allowed for significant cold air to spill southward from Canada. The storm quickly intensified as warm moist air from the Gulf of Mexico collided with this cold air, leading to rapid cyclone development (Kocin & Uccellini, 2004).

Compared to average midlatitude cyclones that typically progress with moderate intensity, the Superstorm rapidly escalated, producing extreme snowfall over a vast area, with blizzard conditions reported in states like Pennsylvania and New York. It caused over 300 million dollars in damages, with hundreds of casualties (Rogers & Schor, 1993). The scope and intensity of this storm were largely due to its unique meteorological setup combined with the sheer scale that set it apart from typical cyclones.

Preventative measures might have included enhanced forecasting models that could predict such an extreme convergence of air masses. Improved emergency management responses could have better equipped communities to handle the event, potentially reducing casualties and damage. Overall, the storm showcased the need for continuous improvement in meteorological prediction and preparedness strategies (National Weather Service, 1993).

Conclusion

Midlatitude cyclones are crucial systems with significant implications for weather, safety, and ecosystems. Understanding their life cycles and the general circulation of the atmosphere allows for improved forecasting and preparedness strategies. The Superstorm of 1993 serves as a critical case study, highlighting both the potential for severe impacts and the need for better meteorological understanding and preparedness to mitigate future disasters.
