aSurface temperature differences in turn cause pressure differences. A hot surface heats the air above it and the air expands, lowering the air pressure. The resulting horizontal pressure gradient accelerates the air from high to low pressure, creating wind, and Earth's rotation then causes ...
Instead of more conventional evaluations based solely on a TC's maximum wind speed or minimum sea level pressure (MSLP), the relationship between these two variables is used: a TC's pressure-wind relationship (PWR), which gives a more detailed look at how well each model analyzes and ...
Alveoli are the site of gas exchange within the lungs, and they are small enough to prevent the flow of air. When oxygen reaches the alveoli, it must instead diffuse across a membrane. This means that it will leave the lungs (where the partial pressure of oxygen is high) and enter the...
Movement in the water - spinning in low-pressure areas of water creates a wave Low wind shear - low wind shear allows a storm to grow large and strong Warm ocean waters lead to warm air above the water. This warm air rises and mixes with cooler air in the atmosphere, creating a thunde...
Anticyclonic weather in European autumn and winter is characterized by low wind speeds and little to no precipitation (Czernecki et al., 2017; Graham et al., 2020). Mesoscale high pressure systems lower atmospheric mixing layer heights (MLH) hindering vertical dispersion of air pollutants, which...
They investigated the mechanisms that cause strong pressure waves in end-gas auto-ignition during knocking. They found that auto-ignition occurs at the wall when the initial temperatures is high, and transitions to the region ahead of the flame front as the initial temperature decreases. Hence, ...
pressure. If the flow path is divided into several infinite layers, the fluid layers in laminar flow stay parallel to each other without mixing or disrupting the path of the adjacent layers. This very nature of the flow makes the use of laminar, low-velocity air circulation systems ...
We have used a newly developedon-site cell-specific analysis(see Fig.S1in Wadaet al. 2019)18to make this analysis possible. This analytical method consists of single cell metabolomics, called ‘picolitrepressure-probe-electrospray-ionizationmassspectrometry (picoPPESI-MS)’19and accurate environmental...

Simply put, weather denotes the daily atmospheric condition, concerning various elements like temperature, precipitation, moisture, cloudiness, wind velocity and air pressure. It expresses the position of the atmosphere at a specified place and time, in degrees, i.e. hot or cold, clear or cloudy...
