    Characteristics of tropical cyclones in high-resolution 1 models in the present climate (2015)
    Details
    Publication Date: 2021-06-16
    Description: The global characteristics of tropical cyclones (TCs) simulated by several climate models are analyzed and compared with observations. The global climate models were forced by the same sea surface temperature (SST) fields in two types of experiments, using climatological SST and interannually varying SST. TC tracks and intensities are derived from each model's output fields by the group who ran that model, using their own preferred tracking scheme; the study considers the combination of model and tracking scheme as a single modeling system, and compares the properties derived from the different systems. Overall, the observed geographic distribution of global TC frequency was reasonably well reproduced. As expected, with the exception of one model, intensities of the simulated TC were lower than in observations, to a degree that varies considerably across models

    Hurricanes and climate: the U.S. CLIVAR working group on hurricanes (2014)
    American Meteorological Society
    Details
    Publication Date: 2021-06-16
    Description: While a quantitative climate theory of tropical cyclone formation remains elusive, considerable progress has been made recently in our ability to simulate tropical cyclone climatologies and understand the relationship between climate and tropical cyclone formation. Climate models are now able to simulate a realistic rate of global tropical cyclone formation, although simulation of the Atlantic tropical cyclone climatology remains challenging unless horizontal resolutions finer than 50 km are employed. This article summarizes published research from the idealized experiments of the Hurricane Working Group of U.S. CLIVAR (CLImate VARiability and predictability of the ocean-atmosphere system). This work, combined with results from other model simulations, has strengthened relationships between tropical cyclone formation rates and climate variables such as mid-tropospheric vertical velocity, with decreased climatological vertical velocities leading to decreased tropical cyclone formation. Systematic differences are shown between experiments in which only sea surface temperature is increased versus experiments where only atmospheric carbon dioxide is increased, with the carbon dioxide experiments more likely to demonstrate the decrease in tropical cyclone numbers previously shown to be a common response of climate models in a warmer climate. Experiments where the two effects are combined also show decreases in numbers, but these tend to be less for models that demonstrate a strong tropical cyclone response to increased sea surface temperatures. Further experiments are proposed that may improve our understanding of the relationship between climate and tropical cyclone formation, including experiments with two-way interaction between the ocean and the atmosphere and variations in atmospheric aerosols.

    Tracking Scheme Dependence of Simulated Tropical Cyclone Response to Idealized Climate Simulations (2014)
    American Meteorological Society
    Details
    Publication Date: 2017-04-04
    Description: Future tropical cyclone activity is a topic of great scientific and societal interest. In the absence of a climate theory of tropical cyclogenesis, general circulation models are the primary tool available for investigating the issue. However, the identification of tropical cyclones in model data at moderate resolution is complex, and numerous schemes have been developed for their detection. We here examine the influence of different tracking schemes on detected tropical cyclone activity and responses in the Hurricane Working Group experiments. These are idealized atmospheric general circulation model experiments aimed at determining and distinguishing the effects of increased sea-surface temperature and other increased CO2 effects on tropical cyclone activity. We apply two tracking schemes to these data and also analyze the tracks provided by each modelling group. Our results indicate moderate agreement between the different tracking methods, with some models and experiments showing better agreement across schemes than others. When comparing responses between experiments, we find that much of the disagreement between schemes is due to differences in duration, wind speed, and formation-latitude thresholds. After homogenisation in these thresholds, agreement between different tracking methods is improved. However, much disagreement remains, accountable for by more fundamental differences between the tracking schemes. Our results indicate that sensitivity testing and selection of objective thresholds are the key factors in obtaining meaningful, reproducible results when tracking tropical cyclones in climate model data at these resolutions, but that more fundamental differences between tracking methods can also have a significant impact on the responses in activity detected.

    Transient hole-burning and time-resolved fluorescence spectra of dye molecules in solution: Evidence for ground-state relaxation and hole-filling effect (1992)

    Notes: A picosecond transient hole-burning (THB) spectroscopy has been performed for organic dyes in solution. The THB spectra of rhodamine 640 have been found to show a time-dependent spectral change. This phenomenon corresponds to the solvent relaxation effect observed in the time-resolved fluorescence (TRF) spectrum. Although TRF spectrum is related only to the excited-state relaxation, THB spectrum is affected by both ground- and excited-state relaxations. Comparing with the TRF spectrum measured under the same exciting energy, we have clarified the presence of the ground-state relaxation. Further, the THB spectrum of styryl-8 gives an antihole between well-separated two holes corresponding to ground- and excited-state contributions. This may originate from the hole-filling effect due to the nonadiabatic relaxation from the nonequilibrium excited state to the ground state. The analysis based on a configuration coordinate model gives an overall understanding for these phenomena.

    Notes: We have studied stable structures of hydrogenated Si clusters grown from silane gas in an ion trap developed for cluster growth. The grown clusters were extracted from the ion trap through two different pathways and were analyzed by mass spectrometers. The Si6Hx+ cations were stably grown, among them clusters with x=1, 7, and 13 were always observed, regardless of the growth conditions or the extraction pathways. The stable structures of these clusters were theoretically investigated. Clusters of x=1, 7, and 13 corresponded to the compact structure, the intermediate structure which has both compact and bulklike configurations, and the bulklike sp3 structure, respectively. © 1997 American Institute of Physics.

    INFLUENCES OF COLCHICINE, VINBLASTINE AND CYTOCHALASIN ON THE RELEASE OF 5-HYDROXYTRYPTAMINE FROM RAT BRAIN SYNAPTOSOMES (1978)

    Notes: Rat brain synaptosomes preincubated with [3H]5-HT. were further incubated and the release of [3H]5-HT from the preparation was studied. The spontaneous release consisted of an initial rapid phase followed by slower release. Incubation with 60 mM-KCl increased the release while 60 mw-NaCl did not affect it. The effect of KG was abolished when NaCl was omitted from the medium. The potassium-induced release was Ca2+ -dependent while that induced by tyramine (10−5-10−4M) and the spontaneous release did not depend on Ca2+. Vinblastine (10−5–2.5 X 10−4 M) caused an increase in the spontaneous release and an decrease in the potassium-induced release, while it completely inhibited the release by tyramine at 2.5 X 10−4 M. Colchicine (5 X 10−5–10−3M) and cytochalasin D (10−5, 10−4 M) failed to produce any change in the release. Cytochalasin B (10−5, 10−4M) increased the spontaneous release and decreased the potassium-induced release but it did not affect the release by tyramine. Colchicine (10−3 M). vinblastine (10−4 M) and cytochalasin B (10−4 M) did not affect significantly Na+.K+-. Mg2- and Ca2+ -ATPase activities. These results suggest that none of microtubules. microfilaments and contractile protein participates in the mechanism of [3H]5-HT release from synaptosomes, in vitro.

    Effects of growing leafy daikon (Raphanus sativus) on populations of Plasmodiophora brassicae (clubroot) (2000)

    Notes: Control of some soilborne pathogens may be achieved by use of decoy or catch crops. These stimulate the germination of resting spores, resulting in limited expression of disease symptoms. Results achieved using this approach are reported here using leafy daikon (radish, Raphanus sativus var. longipinnatus) for control of Plasmodiophora brassicae, the cause of clubroot disease of Brassicaceae. Disease indices of Chinese cabbage plants grown in pots that had previously contained leafy daikon were lower compared with pots where no plants had been grown before (control pots). Numbers of resting spores of P. brassicae in soil in pots after cultivation with leafy daikon were reduced by 71% compared with control pots when resting spores were recovered and counted directly. In a field experiment, numbers of resting spores were reduced by 94% compared with the start of the experiment when leafy daikon was grown in advance of Chinese cabbage, but there was no reduction in disease severity in the Chinese cabbage. Plasmodiophora brassicae infected the root hairs of leafy daikon and those of Chinese cabbage, but no clubs were found on leafy daikon roots. The results from pot trials indicate that leafy daikon may be useful as a decoy crop for the control of clubroot disease in field crops.

    A circular dichroism study of the effect of some organic solvents on the actomyosin of sardine (Sardinops melanosticta) (1988)

    Notes: Circular dichroism (CD) was used to study changes in conformation of sardine (Sardinops melanosticta) actomyosin after treatment with some organic solvents. Untreated sardine actomyosin showed two negative bands at 208 and 222 nm, typical of proteins possessing α-helix configurations. The water-miscible alcohols methanol, ethanol, isopropanol and n-butanol, and the water-immiscible solvents n-hexane, n-octanol, and dichloromethane altered the native conformation of sardine actomyosin. The degree of alteration of native sardine actomyosin was principally dependent on the alcohol concentration and temperature used for dewatering. The least damage occurred with isopropanol, or with 10 or 90% aqueous ethanol; most damage occurred with 40–50% aqueous ethanol. Dichloromethane and n-butanol increased the α-helical content of the native protein. Treatment with hydrophilic and hydrophobic solvents at 70 and 20°C unfolded the protein to form a random coil, but defatting treatment at 2°C caused little damage.
