Irregularity of temperature and humidity condition of underlying surface and orograpy are the most important factors, influencing thunder activity in both regions.
There is a suggestion that inadvertent human influences may also relate to the decrease in thunder activity in the eastern United States.
The combination of reconstruction, separation, and frequency analysis provides new insights on the origin of thunder.
The analysis also confirmed well known seasonal and regional patterns of thunder activity.
A consideration of the sound properties of thunder suggests that atmospheric effects are probably minor, however further research is recommended.
Even with these problems, the gross features of thunder can be explained qualitatively and there is hope that future experiments will provide information necessary to correct for propagation effects making the study of thunder a useful tool for testing theoretical models of lightning.

Is body height environmentally influenced?
5 answers
Body height is influenced by a combination of genetic and environmental factors. Environmental conditions, such as nutrition, diseases, and socioeconomic status, play a significant role in determining body height. Studies suggest that in modern Western societies, around 20% of the variation in body height is due to environmental factors, with a larger impact in poorer environments. Additionally, childhood living conditions, including nutrition and diseases, have a substantial impact on growth and adult body height. While genetics become increasingly important in explaining height variation from childhood to adolescence, environmental factors, especially in early childhood, remain crucial, emphasizing the need for family and social interventions to address height discrepancies.
What is a tornado?
5 answers
A tornado is defined as a violently rotating column of air in contact with the ground, often visible as a funnel cloud, and is a significant natural disaster causing damage primarily through extreme winds exceeding 300 mph. Tornadoes can be spawned by storms associated with tropical cyclones and hurricanes, with the majority occurring in North America but having global reach. Tornadoes are a major public health concern due to their destructive potential. Various applications of the term "Tornado" exist beyond meteorology, such as a heterogeneous programming framework for managed languages that dynamically configures applications for specific systems, achieving significant speedups without code modifications. Additionally, Tornado is used as a distributed in-memory spatio-textual stream processing system, enhancing performance by dynamically redistributing workloads based on changes in data distribution.
What is the relationship between geomagnetic indices and space weather events?
4 answers
Geomagnetic indices play a crucial role in understanding and predicting space weather events. Different indices like Dst, SYM-H, and SMR provide insights into geomagnetic disturbances during extreme space weather events. Studies show that the return levels of SYM-H and SMR diverge from Dst as the return period increases, with SYM-H and SMR exceeding Dst at longer return periods. Additionally, the GIC index, calculated from geomagnetic field variations, correlates with Storm Sudden Commencements, highlighting its importance in assessing GIC risks during magnetic storms. Furthermore, the variation of geomagnetic indices across solar cycles aids in quantifying space weather risk, emphasizing the need to understand how events of a given size vary with solar cycle strength for effective space weather risk assessment.
Why 2022 was extreme precipitation in china?
4 answers
The extreme precipitation events in China in 2022 were attributed to severe natural disasters like floods, with the Guangdong Province experiencing the strongest, broadest, and longest rainfall event in recent years. This extreme precipitation led to significant losses to local people and property. Additionally, the research on extreme precipitation events in China has shown an increase in frequency and intensity, impacting agricultural production and vegetation coverage. The extreme precipitation events were influenced by various factors, including synoptic-scale disturbances, moisture transport, and potential vorticity intrusion in the upper levels of the atmosphere. The occurrence of such extreme precipitation events underscores the importance of understanding the causes and trends of extreme precipitation under the backdrop of climate change for effective disaster management and mitigation strategies.
What is the characteristic of Cumulonimbus cloud?
4 answers
The characteristics of a Cumulonimbus cloud include high atmospheric instability, rotational motion sinking before waterspout generation, and specific radar identifiers like the "Zdr column" and zones with varied Doppler velocity values. Additionally, the transition of convective clouds to the Cumulonimbus stage results in increased cloud depth and reflectivity, with varying changes in different regions like Russia and India. Furthermore, the occurrence of large ice particles in the cloud at the onset of thunderstorm activity and the presence of extended updrafts associated with waterspouts are notable features observed through radar measurements. Moreover, the impact of aerosols on Cumulonimbus cloud evolution, especially in enhancing ice formation and precipitation, is highlighted in studies involving heavy pollution scenarios.
How does extreme weather affect asthma symptoms and exacerbations in different populations?
5 answers
Extreme weather, influenced by climate change, significantly impacts asthma symptoms and exacerbations in various populations. Increased precipitation, linked to climate change, can lead to higher airway inflammation and asthma exacerbations, especially in adolescents with asthma and outdoor allergen sensitivities. Temperature fluctuations, particularly cold fronts, are associated with thunderstorm asthma epidemics, affecting susceptible individuals. Moreover, lower temperatures, especially in winter, can increase asthma cases, highlighting the role of temperature as a key factor in asthma exacerbations. Additionally, pollen and aeroallergens, influenced by climate change, are on the rise, contributing to asthma exacerbations during extreme weather events like thunderstorms. Understanding these climate-related risk factors is crucial for developing effective prevention and management strategies for asthma in different populations.
Why clod point tropopuse height lower during summer and higher during winter?
5 answers
The cold point tropopause height is lower during summer and higher during winter due to various factors. In the tropics and subtropics, convective storm top altitudes are lower in summer, leading to a lower cold point tropopause height. Additionally, the Earth-atmosphere system's angular momentum conservation causes a difference in the Length of Day (LOD) between winter and summer, influencing atmospheric dynamics and tropopause height. Furthermore, in patients with renal bone disease, kidney function and biochemical indexes show seasonal variations, affecting physiological processes that can impact tropopause height. Moreover, clinical studies on pediatric pneumonia treatment suggest that point application in summer for prevention in winter can reduce attack frequency, potentially influencing respiratory conditions that may impact tropopause height. Lastly, orthostatic tests on hypertensive patients show variations in blood pressure between winter and summer, reflecting seasonal physiological changes that can affect atmospheric conditions and tropopause height.
What approach is effective in control landslides between and forest restoration and progressive terraces?
5 answers
The most effective approach in controlling landslides between forest restoration and progressive terraces is to apply structural measures over potentially unstable slopes in the short term, while promoting the development of agricultural or forestry practices on terraced slopes in the long term. Structural measures can reduce landslide risk in the immediate future, while agricultural or forestry practices on terraced slopes can help prevent the degradation of terraced areas and decrease landslide frequency over time. This combined approach takes into account the complex interaction between environmental, historical, cultural, and socio-economic aspects, and provides the best strategy for reducing landslide risk and ensuring the long-term stability of the landscape.
How will big data analytics be used for hurricane predictions?
5 answers
Big data analytics is being used for hurricane predictions by utilizing machine learning and data-driven models. These models are trained on building, hazard, and geospatial data to forecast the damage that buildings will experience during hurricanes, aiding in decision-making for community stakeholders. Additionally, statistical and machine learning models have been developed to predict the extent of power disruptions caused by hurricanes, using inputs such as power system information, environmental factors, and demographic parameters. Real-time crash risk prediction during hurricane evacuation is also possible using connected vehicle data, which contains vehicle location, speed, and acceleration information collected at high frequencies. Furthermore, machine learning and deep learning techniques are employed to simulate important hurricane properties, such as landfall location and wind speed, based on input data from the HURDAT2 database. These applications of big data analytics contribute to improving hurricane predictions and enhancing preparedness and response efforts.
What is the problem of ahp?
5 answers
The problem with AHP is the rank reversal issue, where the introduction of a replica of an alternative can cause a change in the rank order among alternatives. Another problem is the inconsistency in the decision-maker's preferences, which can be caused by intransitivity and limitations of the 1-9 ratio scale. Critics argue that the AHP method as a whole is erroneous and cannot be applied in practice. However, proponents believe that the disadvantages of the method can be overcome by using a rating method and by checking adequacy. AHP also faces scalability issues, which can be problematic when dealing with large numbers of requirements. To address these problems, an enhanced version of AHP called E-AHP has been proposed, which is more scalable, produces more consistent and accurate results, and is suitable for large software projects.
How does stature change with age?
5 answers
Stature changes with age, showing a decline in linear body dimensions as individuals grow older. This decline in stature is attributed to both the ageing effect and secular trend in height gain in younger generations. Studies have shown that the decline in stature accelerates in the fifth decade and continues to decline in subsequent decades. There is also a significant sex difference, with females declining at a greater rate than males, particularly after the age of 40. The rate of decline in stature is approximately -0.20cm/year for males and -0.34cm/year for females. However, it is important to note that the effect of secular trend on stature is minimal.
