Bu çalışmada, Samsun ili için sıcak ve soğuk hava dalgalarının zamansal olarak analizleri yapılmıştır. Çalışma kapsamında, sınırları içerisinde yer alan, Merkez Bafra meteoroloji gözlem istasyonlarından 1990-2019 yılları arasındaki dönem temin edilen maksimum minimum sıcaklık verileri kullanılmıştır. Sıcak tespiti sırasında sıcaklıklarının 90. persentil değerleri hesaplanarak referans alınmıştı...

Viscous profiles of shock waves in systems of conservation laws can be viewed as heteroclinic orbits in associated systems of ordinary differential equations (ODE). In the case of overcompressive shock waves, these orbits occur in multi-parameter families. We propose a numerical method to compute families of heteroclinic orbits in general systems of ODE. The key point is a special parameterizat...

OBJECTIVE To investigate the relationship between temperature extremes and daily number of deaths in Jinan, a temperate city in northern China. METHODS Data ondaily number of deaths and meteorological variables over the period of 2011-2014 were collected. Cold spells or heat waves were defined as ≥3 consecutive days with mean temperature ≤5th percentile or ≥95th percentile, respectively. We a...

OBJECTIVES From August 1st to 20th, 2003, the mean maximum temperature in France exceeded the seasonal norm by 11-12 degrees C on nine consecutive days. A major increase in mortality was then observed, which main epidemiological features are described herein. METHODS The number of deaths observed from August to November 2003 in France was compared to those expected on the basis of the mortali...

greece has experienced particularly severe and frequent forest fires during summer 2007 together with exceptionally dry meteorological conditions culminated in distinct heat waves. the present study analyzes the time pattern of daily values of two fire risk indices (nesterov and angstrom) based on meteorological data made available for a number of gauging stations between 1 june and 31 august o...

introduction: human eye is a sensitive part of human body with no direct protection and due to its lack of protection against the external heat waves, studying the temperature distribution of heat waves on the human eye is of utmost importance. various lasers are widely used in medical applications such as eye surgeries. the most significant issue in the eye surgeries with laser is estimation o...

A modeling study on the energy absorption and heat transfer of concentric nanoparticles under localized surface plasma resonance (SPR) conditions is presented. A generalized theoretical formulation for multi-scattering of electromagnetic waves by multilayered nanoparticle is employed to determine the heat source first, and then starting with the Eigen functions, direct and inverse integral tran...

A model interpreting variations of EUV brightness upward propagating in solar coronal loops as slow magnetoacoustic waves is developed. A loop is considered to have a non-zero plane inclination angle and offset of the circular loop centre from the baseline. The model also incorporates effects of dissipation and gravitational stratification. A linear evolutionary equation is derived and applied ...

Extreme climatic events (ECEs) such as droughts and heat waves are predicted to increase in intensity and frequency and impact the terrestrial carbon balance. However, we lack direct experimental evidence of how the net carbon uptake of ecosystems is affected by ECEs under future elevated atmospheric CO2 concentrations (eCO2). Taking advantage of an advanced controlled environment facility for ...
