Arctic Sea Ice Extent (Area of ocean with at least 15% sea ice)
Glaciers Since 1980, a representative set of well studied glaciers has lost the equivalent of 40ft.(12.5m) of water on average. The graph shows the average mass balance of 30 reference glaciers around the world.
Temperature Earth’s overall temperature has increased by 1.3°F (0.7°C) since 1900. In the graph, average annual surface temperature is shown as the difference from the average for 1901-2000.
Spring Snow Cover Earlier melting of winter snow has reduced the area of land covered by snow in spring. The graph shows the area covered by snow in the N. Hemisphere during March and April, shown as the difference from the 1971-2000 average.

Ocean Heat More than 90% of the warming that has occurred on Earth over the past 50 years has occurred in the ocean. The graph shows heat energy in the top 700m of the ocean as the difference from the average from 1955-2006.
Sea Level The average height of the ocean’s surface has increased by 8.25”(210 mm) since 1880. The graph shows mean global sea level measured by tidal gauges since 1880 and by satellite instruments since 1993.

Arctic Sea Ice The area of the Arctic where sea ice remains frozen at the end of summer has decreased by more than 10% per decade since 1979. The graph shows the average area with at least 15% sea ice on its surface each September.

Weather derivatives at a glance
A weather derivative is typically a European style capped option on a climate parameter. At expiry of the contract is cash settled, based on the measurements of the national meteorological office. Standard weather derivative contracts are defined by the following attributes:
Contract period Weather measurement station Weather variable or underlying Index which aggregates the weather variable Payoff function, which converts an index into the cash flow Premium Key difference to most other options: YOU CANNOT TRADE THE UNDERLYING – NO DELTA HEDGING No Black-Scholes-Merton
20
6 Terms you need to be familiar with
Weather Station, Risk Period, Weather Trigger (Threshold), Strike (Excess), Defined Payout per Index Point, Maximum Payout
1. The Weather Station is the official measurement station operated by the met office
which is used for price calculation and settlement.
2. The period from Start Date to End Date is the Risk Period.
3. The Weather Trigger (Threshold) defines when a day counts as a Critical Day. (Weather derivative indices can have none, one or multiple thresholds)
4. The Strike defines the amount of Index Points of own risk. The option starts to pay once the number of cumulative Index Points during the Risk Period exceeds the Strike.
5. The Payout per Index Point is the amount paid for every Index Point in excess of the Strike.
6. The Maximum Payout is the cap of the option. 21
Weather Station: London Heathrow Risk Period: 01.11.2011 – 29.03.2012 (weekdays only) Threshold: -2.0°C Average/StDev: 8/4 Frost Days Excess (Strike) normally set between average (At-the-Money) and average + 1.5 StDev (Out-of-the-Money). Limit of Cover (Maximum Payout) is the product of: (Payout per index point * (Exit - Strike)). The exit is normally set as historical extreme or average + 4-8 StDev. Example: Payout per Frost Day: 10‘000 *(Exit: 38 Frost Days – Strike: 8 Frost Days) = Max Payout: 300‘000

Payout Function
Payout Function Example: Strike: 8 Critical Days; Payout per Critical Day: 10k, Limit of Cover: 300k Payout Formula: The higher of zero or ((Number of Critical Days at End Date – Excess) * Payout per Critical Day), limited by the Limit of Cover (Max. Payout)
Example: Strike: 8 Payout per Critical Day: 10k Maximum Payout: 300k Critical Frost Days @ Expiry: 20 -> Payout: 120k Critical Frost Days @ Expiry: 7 -> Payout: 0 :

Weather hits harvest
7. Sept 2011, LONDON (ShareCast) - Shares in Landkom wilted after lower than expected yields from its rapeseed harvest prompted the grain and oilseeds grower to “review its strategic options.” Rapeseed harvest reduced due to "a combination of earlier hail damage and heavy rains.”
Station: Ukraine, Lviv, rain day index (rainfall > 2 mm) during harvest season (28.06 – 10.08.2011)
Consequence: 2011 rapeseed harvest is below
expectation and quantity sold forward.
Landkom is 2,275 tonnes short of rapeseed.
Share price plummets -38%

Energy – Electricity Prices in Victoria, AU
The demand for electricity is highly weather dependent. Cold winter weather increases the demand for energy used for heating. Hot summer weather increases the demand for energy used for cooling.
Vicoria has predominantly fossil fired energy production (Cole and gas), no Nukes and very little Hydro power. Power is exchange traded at d-cyphaTrade Exchange on a 30 min basis.

Heat Day –
Daily energy demand is highly correlated with T-max. Between Jan. 8-12. 2010, T-max exceeded 43 C°. Energy demand spiked 30% as a result.
