“…Field surveys have certainly given more accurate data on tornado path lengths. Other factors for a more systematic reporting of weak tornadoes over time (Brooks and Doswell, 2001) include a general improvement of public awareness and increasing urbanization.…”

Abstract. The standard measures of the intensity of a tornado in the USA and many other countries are the Fujita and Enhanced Fujita scales. These scales are based on the damage that a tornado causes. Another measure of the strength of a tornado is its path length of touchdown, L. In this study we consider severe tornadoes, which we define as L ≥ 10 km, in the continental USA (USA Storm Prediction Center Severe Weather Database). We find that for the period 1982-2011, for individual severe tornadoes (L ≥ 10 km): (i) There is a strong linear scaling between the number of severe tornadoes in a year and their total path length in that year. (ii) The cumulative frequency path length data suggests that, not taking into account any changing trends over time, we would expect in a given year (on average) one severe tornado with a path length L ≥ 115 km and in a decade (on average) one severe tornado with a path length L ≥215 km. (iii) The noncumulative frequency-length statistics of severe tornado touchdown path lengths, 20 < L < 200 km, is well approximated by an inverse power-law relationship with exponent near 3.

“…Brooks and Doswell (2001) showed that the distribution of tornadoes by (E)F-scale for the U.S. compared with several other countries 1 is similar for (E)F-3 and higher intensity events. The Weibull distribution has been shown to model observed tornado intensities (Dotzek et al, 2003) as well as path length and width (Brooks, 2003a).…”

a b s t r a c t a r t i c l e i n f oThis paper investigates the environmental parameters favoring significant tornadoes in Bangladesh through a simulation of ten high-impact events. A climatological perspective is first presented on classifying significant tornadoes in Bangladesh, noting the challenges since reports of tornadoes are not documented in a formal manner. The statistical relationship between United States and Bangladesh tornado-related deaths suggests that significant tornadoes do occur in Bangladesh so this paper identifies the most significant tornadic events and analyzes the environmental conditions associated with these events. Given the scarcity of observational data to assess the near-storm environment in this region, high-resolution (3-km horizontal grid spacing) numerical weather prediction simulations are performed for events identified to be associated with a significant tornado. In comparison to similar events over the United States, significant tornado environments in Bangladesh are characterized by relatively high convective available potential energy, sufficient deep-layer vertical shear, and a propensity for deviant (i.e., well to the right of the mean flow) storm motion along a low-level convergence boundary.

Insurability of Climate Risks

The IPCC 2007 report noted that both the frequency and strength of hurricanes, floods and droughts have increased during the past few years. Thus, climate risk, and more specifically natural catastrophes, are now hardly insurable: losses can be huge (and the actuarial pure premium might even be infinite), diversification through the central limit theorem is not possible because of geographical correlation (a lot of additional capital is required), there might exist no insurance market since the price asked by insurance companies can be much higher than the price householders are willing to pay (short-term horizon of policyholders), and, due to climate change, there is more uncertainty (and thus additional risk). The first idea we will discuss in this paper, about insurance markets and climate risks, is that insurance exists only if risk can be transferred, not only to reinsurance companies but also to capital markets (through securitization or catastrophes options). The second one is that climate is changing, and therefore, not only prices and capital required should be important, but also uncertainty can be very large. It is extremely difficult to insure in a changing environment.
