A shortwave or shortwave trough is an embedded kink in the Troughmeteorologytrough Ridge meteorology ridge pattern. This is the opposite of Rossby wave longwaves , which are responsible for Synoptic scale meteorology synoptic scale systems, although shortwaves may be contained within or found ahead of longwaves and range from the Mesoscale meteorology mesocale to the synoptic scale. Shortwaves are most frequently caused by either a cold pool or an upper level Weather front front . Corresponding weather and effects Shortwaves are often associated with warm WAA or cold air advection CAA , which influence temperature. Due to the way they curve the air that moves around them and the way air moves away from them, shortwaves produce positive curvature vorticity and positive shear vorticity, respectively. Ahead of a shortwave there is large scale lift due to divergence from positive vorticity advection PVA . This lift often sparks Precipitation meteorology precipitation . In a Convective inhibition capped environment , the lift generated by a shortwave may cool the inversion layer through Adiabatic cooling Adiabatic heating and cooling adiabatic cooling , allowing for deep, moist Atmospheric convection convection .

Mesoscale meteorology is the study of weather systems smaller than synoptic scale systems but larger than Microscale meteorology microscale and storm scale cumulus systems. Horizontal dimensions generally range from around 5 kilometers to several hundred kilometers. Examples of mesoscale weather systems are sea breeze s, squall line s, and mesoscale convective complex es. Vertical velocity often equals or exceeds horizontal velocities in mesoscale meteorological systems due to nonhydrostatic processes such as buoyant acceleration of a rising thermal or acceleration through a narrow mountain pass. Subclasses Mesoscale Meteorology is divided into these subclasses Orlanski, 1975 Meso gamma 2 20 km, deals with phenomena like thunderstorm convection, complex terrain flows at the edge to Microscale meteorology microscale , also known as storm scale Meso beta 20 200 km deals with phenomena like sea breezes, lake effect snow storms Meso alpha 200 2000 km fronts, deals with phenomena like squall lines, mesoscale convective systems MCS , tropical cyclones at the edge of synoptic scale Mesoscale boundaries As in surface weather analysis synoptic frontal analysis , literature about mesoscale analysis uses cold, warm, and occluded fronts on the mesoscale to help describe phenomena. On weather maps mesoscale fronts are depicted as smaller and with twice as many bumps or spikes as the synoptic variety.

Pneumatic troughs require a liquid such as water. Scientists also have used mercury in pneumatic troughs, but usually only for the collection of water soluble gases. Health and safety issues surrounding mercury generally prohibit its use in modern day pneumatic troughs.

Disadvantage of the pile Volta s battery consisted of brine soaked pieces of cloth sandwiched between zinc and copper discs, piled in a stack. This resulted in electrolyte leakage as the weight of the discs squeezed the electrolyte out of the cloth. Advantage of the trough Cruickshank solved this problem by laying the battery on its side in a rectangular box. The inside of this box was lined with shellac for insulation, and pairs of welded together zinc and copper plates were laid out in this box, evenly spaced. The spaces between the plates the troughs were filled with dilute sulfuric acid . So long as the box was not knocked about, there was no risk of electrolyte spillage.
