\subsection{Survey of Existing Approaches} \label{ssec:existing} Because few remote control (RC) setups allow for live telemetry‚ almost all flying is done "by eye‚" and RC instrumentation and data logging is a poorly developed field. RC gliders especially eschew any projecting elements which could increase drag. The few relevant RC systems the author has found are described in this section‚ but most considered designs are in practice found only on manned vehicles. \begin{figure}[!htb]

Storm Surges and Winds STEPHANIE SMITH Executive Summary On October 22‚ 2012‚ it was announced by The Office of Disaster Preparedness and Emergency Management (ODPEM‚) that a tropical depression (Sandy) was headed towards the shores of Jamaica and that the arrival to our shores would be on October 24. On the 24th Sandy approached and the effects were devastating. The winds caused several trees to plummet‚ taking down power lines‚ utility poles and homes with them. The winds blew roof tops

when sea temperatures are at their highest. Hurricanes only form over really warm ocean water of 80°F or warmer. The atmosphere (the air) must cool off very quickly the higher you go. Also‚ the wind must be blowing in the same direction and at the same speed to force air upward from the ocean surface. Winds flow outward above the storm allowing the air below to rise. Day after day the fluffy cumuli form atop die updrafts. But the cloud tops rise higher than about 6‚000 feet. At that height in the

In the distance‚ the roll of clouds could be seen as they filled the sky above; covering all light that now couldn’t be seen.

Generally‚ the sound of hurricane force winds and snapping trees don’t combine to make the sweetest lullaby but for the hurricane season those sounds rocked me to sleep. Mix with my mother’s panic and some house leaks‚ I didn’t necessarily have the most eventful hurricane experience. The approach of hurricane Irma didn’t make me as nervous as much as it should have‚ most likely due to my mother worrying enough for the both of us. We covered everything important and not so important things in plastic

Wildfires are large‚ destructive fires that spread quickly across woodland or brush. These fires are powered by the weather‚ wind‚ and dry underbrush. Tons and tons of land can be burned‚ leaving everything in its path destroyed. This all can happen in just a matter of minutes. Uncontrolled blazes‚ or wildfires “can clear four million to five million acres of land in the U.S. every year (Wildfires‚ 2015).” During a wildfire‚ it moves at a speed of around fourteen miles an hour. While it’s burning

1002 The Cause & Effect of Hurricanes Hurricanes are the most destructive natural disasters in the world. They are very powerful and violent storms that have strong winds. Storms are known to be hurricanes when they reach 74 mile per hour. Hurricanes storms start over warm sea water near the equator and come with strong winds‚ flash floods‚ mudslides‚ and huge waves. Hurricanes come with different names depending where the location it occurred. Hurricane storms are called hurricanes‚ if they

which both cause heavy amounts of damage and are uncontrollable. There are many similarities in how hurricanes and tornadoes are formed. Although they are distinct disasters‚ hurricanes‚ and tornadoes pose similar threats to resources because of high winds which can destroy properties and affect the economy along with people’s lives. Both the hurricane‚ and the tornado are rated on a category scale. First‚ devastating‚ and deadly natural disaster is a hurricane. In order for a hurricane to form it

called upon the wind to make the decision. The wind blew hardest. The mango tree stood fast. It would not yield. It knew it was strong and sturdy. It would not sway. It was too proud. It was too sure of itself. But finally its root gave way‚ and it tumbled down. The bamboo tree was wiser. It knew it was not as robust as the mango tree. And so every time the wind blew‚ it bent its head gracefully. It made loud protestations‚ but let the wind have its way. When finally the wind got tired of blowing
