Although I have no clue how they work, but I remember from Calc I and II, that on the mid term and final exam, if the formula calculations were correct, I'd connect the dots and draw these cool ass curves. :D

It's usually a sigh of relief during a tense moment where u feel your parent's money, your raping the books (i.e. studying), and your guilt trip about that 3 hour PC break you took so u procrastinate and finish the next level in WarCraft; was all worth it. :)

Ah - Calc I Math 101 = 70%
Calc II Math 102 = 60%

both passing marks :D

Don't worry... most people don't even know what derivatives are.. :shifty:

Weather risk management is quantifying, analyzing and hedging against weather-related risk, from hurricanes to even miniscule temperature differences during the day. It's essentially risk management.

One of the interesting new tools used to hedge against weather risk is what they call weather derivatives. These tools range from hedging against said temperature differences within a day, something called heating/cooling degree day weather derivatives, and of course derivatives for snow and rainfall. All of these derivatives could be particulary useful for the agriculture and energy industries, and since it's relatively new, not many people know about these hedging techniques.

I love weather derivatives. :smoke:
What is the impact of two degrees in a summer day on anything, Andy??

    It can make a huge difference if you're an energy company. Two degrees Celsius deviation from a forecasted high could mean not having the optimal amount of power to provide customers electricity to run their air conditioners or millions of kilowats of power being allotted for nothing.

    Moreover, two degrees Celsius can have major implications on whether or not convection occurs, which has bearing on the formation and strength of various types of storms.

    really?? :eek:

    I had no idea about that knowing that I live where no tornadoes ever and no way to make energy better than hitting your hands with each other.

    Don't they have buffer plants for that?

    It's fascinating what a temperature change of one degree Celsius can do to our atmosphere. Sometimes one degree Celsius is what separates severe thunderstorms from mo thunderstorms at all.

    Apparently it's not enough, thus the reason for financial derivatives that hedge against energy offsets.

    You should play this great game called Lemonade Stand. It gives you the opportunity to help predict lemonade sales based on the weather. It will help you get a feel for what your career will be like.

    Man, I watched a Tv show about those kind of things and water dams in Switzerland, they had to calculate what amount of water they should let go to secure the dam, but also maximise their profit when selling the energy they would produce.
    So raining forecasts were pretty important in their analysis between safety and profit.

    Fascinating stuff.

    Considering that it was a 1.5℃ drop that is widely considered to be the root cause for what caused the centuries-old Norse settlement of Greenland to go extinct by the year 1400...

    I say that to strippers giving me lap dances all the time. :faq2:
