As a business owner, here’s something you already know – weather conditions can play significant roles in your venture’s success. That’s especially because weather-related changes affect demand and supply. Unprecedented weather conditions can also cause delays that may give your competitors an advantage over you.

Fortunately, trading weather derivatives is one of the best ways to protect your business against such weather-related losses. Weather derivatives and options have become extremely popular among all kinds of enterprises during the last 20 years.

For example, energy firms can use weather derivatives to reduce the risk of fluctuating temperatures impacting their utility, power, and energy businesses’ demand and supply. Meanwhile, weather derivatives trading serves as a form of risk management for insurance firms, hedge funds, and even governments.

In this article, the brokerschart.it experts focus on showing you how you can trade the weather like a pro. 

Know the Difference 

The first thing you must learn when trading weather derivatives is the difference between them, weather insurance and commodity derivatives.

Weather insurance and derivatives differ in their payout structure. In weather insurance, you’ll only get benefits after proven loss. That’s because insurance companies are founded on the principle of indemnification. 

However, with weather derivatives, you get paid out whether or not you have incurred a loss. You are eligible for a claim once the weather conditions meet the criteria listed in the index.

Meanwhile, weather and community derivatives differ in terms of volume. While commodity derivatives permit price hedging based on volume, weather derivatives base price hedging on real utilization or yield, both of which don’t depend on volume.

Know the Market 

Now that you know the difference between weather derivatives, you have a fair idea of what you’re going into. The next step is to understand the market. You must know whether your business qualifies and needs to trade weather derivatives.

First, different companies can benefit from trading weather derivatives and options. For example, farming businesses whose crop yield and production depend largely on the weather will be wise to trade weather derivatives. This helps them to reduce their risk of huge losses during extreme weather conditions. Other companies that can benefit from trading weather derivatives include those event management, insurance, shipping, energy, etc. If you or your company is eligible to trade, you can get started by checking information about a reputable broker eToro https://brokerschart.it/migliori-brokers/etoro. Also, it’s a good idea to check the information you need to trade with Plus500 Broker, one of the best in the game (to be found here https://brokerschart.it/migliori-brokers/plus500).

Know What You Can Trade 

Have you verified that your company can benefit from trading weather derivatives? Then the next step is to understand what you can trade and how to set indexes.

Heating Degree Days (HDD), Cooling Degree Days (CDD), and cumulative precipitation are common examples of weather derivatives many businesses use. While energy companies use the HDD index to protect themselves from freezing temperatures, CDD reduces risk during summer. Meanwhile, cumulative precipitation is mostly used by hydro, farming, and shipping businesses that are often affected by rainfall. 

Companies can also wedge against snowfall levels, heatwaves, thunderstorm predictions, etc. Each one has a unique index that acts as the core of the weather derivative.

Understand Price Setting 

The price of weather derivatives typically depends on current weather predictions/conditions, the value of payoffs throughout the previous two to three decades, and a safety net sum to cover damages. You can determine your desired payout amount using these criteria.

Note that in the US, the annual compensation of a trader in weather commodities ranges from $60,000 to $90,000. At the end of the day, the actual value depends on the state you work for, weather patterns, clientage, and the trading strategies you provide for weather options.

The Bottom Line

The weather derivatives market is growing rapidly around the world. And everything tells us that the interest of investors and investment amounts will grow in the near future. The popularity of this type of investment lies largely in the fact that weather instruments are a good way for reducing the risks associated with specific weather conditions. This connection to the weather allows companies to protect profits from adverse environmental conditions which is especially relevant for companies whose activities mainly depend on weather conditions.

Tornadoes are still a poorly understood atmospheric phenomenon, and the main problem is that it is very difficult to study them experimentally. Tornadoes occur quite often, but it is impossible to predict where exactly it will occur next time, so we have to “chase” tornadoes. Mobile laboratories used in such chases are too fragile and collapse before they can reach the center of the tornado and begin to study it.

It has not yet been possible to produce a tornado in a laboratory under controlled conditions either: this would require an experimental setup of hundreds of meters in size. Therefore, all currently available verified information about the physical conditions in the center of the tornado has been obtained by an indirect method. Thanks to radar observations from afar it is possible to measure air speeds in the tornado and based on this to make conclusions about its internal structure.

Note, by the way, that a surprising situation arises: so far, astronomical methods are used to study tornadoes. Being unable to “get into” the phenomenon itself or to reproduce natural conditions in the laboratory, we have to just watch the tornado carefully trying to understand its nature based on our observations. This is exactly the approach of astronomy.

So far we know that in the center of a tornado there is an area of low pressure. In the most powerful tornadoes the pressure difference outside and inside can exceed one tenth of an atmosphere. Actually, the tornado itself is the outside air which under the influence of this pressure difference tries to fill the inside of the tornado but due to the law of conservation of momentum it twists around its axis so strongly that the centrifugal force keeps it away from the center.

It is difficult to say exactly what kind of air currents take place in the center of the tornado as there are no direct reliable experimental observations. It is quite possible that there are vertical currents there, but it is unlikely to be very strong.

Generally speaking, the famous lifting force of the tornado is not due to the fact that the funnel sucks objects into itself, but to the fact that the rotating air column has vertical turbulence. That is, the air does not wind around the funnel in a fixed circle (then there would be no vertical motion) or in a fixed spiral (then the vertical motion would be constant), but has a rapidly changing vertical velocity component.

Since the tornado problem is one of the most important meteorological problems for the United States, considerable money is regularly allocated for their research. There are even plans to build a heavy tank-like vehicle that would be both very heavy and quite nimble. Such a machine would be able to catch up with the tornado, enter its center, and conduct experiments there. So we should be patient: probably, in a year or two, we will know a lot more about the tornado’s innards than we do now.
