Same as Fig. 10 but for northward track type from October to January. M < < WWVsNJ -ss f r y M < < WWVsNJ -ss f r y Fig. 13. Same as Fig. 10 but for northward track type from October to January. The wind fields display the corresponding circulation flow and potential effective local weather systems. In this study, the West Pacific Subtropical High of winter-time may be the critical modulator of TC tracks in this region, specifically during post-winter-monsoon period. Moreover,...

Methods of analysis

The simplest and widely known technique to investigate common periodicities between two series of data is the Fourier Transform, the Fast Fourier transform and Regression Analysis. However, while useful for stationary time series, these methods are not the best for time series that are not of stationary nature ((35) (116), (117)), as those analyzed in this work. A nice description of the limitations and drawbacks of Fourier Analysis, (including the short-time-Garbor or the windowed Fourier...

Factors that influence hurricane damage costs

Most damage from hurricanes is caused by high winds and storm surge, which is the water that a hurricane's wind pushes toward shore. A major hurricane, which would be a category 3, 4, or 5 on the Saffir Sampson Hurricane Scale, has winds that exceed 110 miles per hour. A storm surge of up to twenty-eight feet above average sea level was recorded in Mississippi during Katrina (Masters, 2010). If the storm surge is accompanied with high tide, the damage is even greater. Three interacting elements...

The hurricane Ike evacuation

UTMB emergency management officials and executive leadership began tracking hurricane Ike late in the week of September 1st, and participating in the Texas Division of Emergency Management State Operations Center conference calls with the National Weather Service (NWS) on Sunday September 7th. Predicted paths varied from the lower Rio Grande Valley to the Florida panhandle early on, but it was assumed that a Texas landfall was likely. By Tuesday it was felt that the storm track would make...

Scales

Catastrophic wind damage and subsequent forest recovery are scale-dependent phenomena and both spatial and temporal scales are important in understanding effects of catastrophic winds. As Levin (1992) pointed out, no single mechanism explains pattern on all scales. Consequently, it is essential to clarify both the spatial and temporal scale over which wind damage and recovery patterns occur and are examined. Windstorms are often distributed over a broad range of spatial scales, and certain...

Introduction

The links between the Space Weather and Meteorological Weather have been often discussed not only for the last century ((70) (72)), but also for several centuries ago ((99)), and even before some thousands of years ago ((74)). Correlational works between solar and climatic parameters give often interesting results ((4)). A great deal of efforts have been done to clarify the mechanism of all complicated interconnections between the cosmophysical and climatic phenomena at earth, some of them...

Coherence analysis of terrestrial and cosmophysical forcings

Data.- To assess the long-term relations between space phenomena and indicators of the global climate it is often necessary to use reconstructions of Galactic Cosmic Rays (CR), solar activity (SS) and climate phenomena. Direct measurements of solar activity based on sunspot numbers exist since 1749, but trustable CR data is only available since the 1950s decade when the neutron Monitor Stations began to operate. Records of climatic phenomena exist from the end of the 19th century. For the AMO...

Bogus data assimilation

To better define the vortex structure in hurricane initial conditions, a bogus data assimilation (BDA) scheme is developed in the WRF-Var. The BDA algorithm includes a) bogus vortex construction and error specification, and b) assimilation of the bogus data with the WRF-Var system. In our studies (Xiao et al., 2006 2009b Zhang et al., 2007), the bogus vortex is constructed according to the method of Ueno (1989 1995). There are two components (symmetric and asymmetric) in the bogus observations....

Atlantic hurricanes

Hurricanes are considered one of the most astonishing meteorological phenomena in our planet. Strong winds, clouds of great size and intense storms unite to advance for the ocean and to reach mainland, razing with everything to their passage, fallen trees, damages in buildings, changes in the natural landscape and, fatal victims, are alone some of the consequences that these unpredictable events can generate. Due to the great intensity that they reach, with winds that can overcome the 350 km...

SAR images segmentation based on undecimated wavelet transform and mean shift

Synthetic Aperture Radar (SAR) has been a useful tool in domains such as disaster detection, cartography and crop monitoring. The images usually have inferior illumination quality mainly due to different type of environmental distributions. So the segmentation of different land covered regions is an important but difficult step in SAR image processing. It is also significant to understand how information changes over different scales of SAR image. Undecimated wavelet transform is good in...

WDM6 MAR 72 h

Fields of maximum snow and graupel contents in the WDM6 simulations at t 72 h. Fig. 19. Fields of maximum snow and graupel contents in the WDM6 simulations at t 72 h. Results obtained using the first simulations of landfalling hurricanes and developing tropical depressions using spectral bin microphysics are quite encouraging. The utilization of SBM based on solving microphysical equations showed significant potential for both further investigation of physical processes in tropical...
