The formation of thunder heads and downdrafts and all that convective weather is in the same boat. Branches of physics. Our pattern recognition is hard wired. The large droplets can then collide with small droplets and combine to form even larger drops. Categories : Cloud and fog physics. Therefore, after collisions with N2 and O2 the CO2 molecule may gain sufficient energy to radiate IR and some of the radiated IR photons will reach the ground. I may be way out of line, but I thought we knew about sudden transitions in fluid dynamics. Another possibility is that the water stays in vapor form, even though it is beyond the saturation point, resulting in supersaturation. Along with adiabatic cooling that requires a lifting agent, there are three other main mechanisms for lowering the temperature of the air to its dew point, all of which occur near surface level and do not require any lifting of the air.

Their results appear this week in the journal Physical Review Letters. The value of a certain parameter is more reliable the more satellites are measuring the said parameter. Typical convection upcurrents may allow the droplets to grow to a radius of about 0. These clouds typically have a wispy, feathery look, and are called "cirrus. Nature, London , Look at the pre-Renaissance calendar, you would find the result. Temperate and polar seasons. This would indicate that there is a sharp transition from liquid to vapour state in isolated areas. However, if the air becomes sufficiently moist and unstable, orographic showers or thunderstorms may appear. This generally occurs when the air is relatively cool, because the amount of water vapor that the atmosphere can "hold" is proportional to the air temperature. Evaporative cooling happens when moisture is added to the air through evaporation, which forces the air temperature to cool to its wet-bulb temperature , or sometimes to the point of saturation.

I guess I just need to read the actual paper. As the comparatively warm water gives up heat and moisture to the cold air above, columns of heated air called thermals naturally rise through the atmosphere. Folks, the idea that transitions occur between heat transfer regimes has been understood for many years. The big ones that bust through the Tropopause and dump their heat into the stratosphere help to directly cool the planet. News Developments Ideas. I think the addition of rotation may be adding a lot to the behavior and that may not have been applied before. That was my first thought, I was always fascinated by plumes of cigarette smoke or water spreading out in the kitchen sink. I still enjoy picking it up and marveling at their demonstration of the Principle of Least Action of Ink and Paper. When that happens, physicists say that the symmetry of the system changes.

That said if the CAGW loons incorporate this new turbulent behaviour mechanism into their models what is the bet they will still shout CAGW even if their results just better model the historical record. Meteorology 6 , The range of temperatures that can give rise to icing conditions is defined according to cloud types and altitude levels:. Skip to main content. Nakaya , U. Finally, experimental meteorology opens our eyes to the inherent chaos in non-equilibrium fluid dynamics, proving that the atmosphere is inherently non-deterministic.

Researchers develop at-home coronavirus saliva test Yesterday. Polar stratospheric clouds clouds are seen but rarely in winter at altitudes of 18 to 30 kilometers, while in summer, noctilucent clouds occasionally form at high latitudes at an altitude range of 76 to 85 kilometers. Your message to the editors. Nevertheless, still interesting. However, if the air becomes sufficiently moist and unstable, orographic showers or thunderstorms may appear. The Physics of Clouds Reviews Close Send. Both of these situations in which air cools and becomes saturated when it rises are examples of what is called "adiabatic cooling. He developed math and theory describing weak turbulence, and to say it was applicable to all atmospheric phenomena is a little … disingenuous? Advances in weather radar and satellite technology have also allowed the precise study of clouds on a large scale. I think the addition of rotation may be adding a lot to the behavior and that may not have been applied before. As the temperature differential increases, the convective flow becomes so vigorous that the velocity field becomes turbulent. Moist air is lighter than the surrounding dry air, creating an unstable situation. Skip to main content.

I think there is this fixation with feedbacks particularly a warm atmosphere radiating heat back to the surface, but that almost seems a bit like perpetual motion. Radiation cannot be from non-radiative gases but it can come from CO2 which is a radiative gas.

I saw a fascinating programme on Greenland some 30 years ago where modern scientific criminal forensics were used to determine what happened to the Early Vikings there. Ahlers and his postdoctoral co-workers Ping Wei and Stephan Weiss study turbulent convection, which plays a major role in numerous natural and industrial processes. This means that whatever model we use, however complex we make it, will never be more than a gross estimation of the order of magnitude of reality. Shaw , D.

  • Exam 2: Cloud Physics April 16, 2008 Physical Meteorology 3440
    Name ____________________________ Exam 2: Cloud Physics April 16, 2008 Physical Meteorology 3440 Questions 1-10 are worth 5 points each. Questions 11-15 are worth 10 points each. 1. Rank the concentrations of the following from lowest (1) to highest (3): cloud condensation nuclei (3) cloud droplets (2) raindrops (1) 2. Match the following particles with their typical size cloud condensation nuclei 10 μm cloud droplets 0.1 μm raindrops 1000 μm 3. Why do ice crystals grow at the expense of supercooled water droplets? The saturation vapor pressure over liquid is higher than the saturation vapor pressure over ice. Therefore, the environment will be more supersaturated with respect to ice than with respect to liquid, and the ice crystals will grow more quickly. At some point, the ice crystals may bring S (with respect to ice) down to 1, in which case Sl (with respect to liquid) is less than 1, causing the liquid drops to evaporate. 4. Match the following particles with their most likely means of growth 5 μm cloud drop accretion 5 μm ice crystal aggregation 100 μm dendritic ice crystals in ice cloud depositional growth 500 μm ice crystal in mixed-phase cloud condensational growth 100 μm cloud drop collision-coalescence 5. Fill in the blanks: Not all clouds with temperatures below the freezing point of water contain ice, because of the scarcity of ice nuclei in the atmosphere, and the temperature at which they nucleate ice. As the cloud temperature decreases, the probability of ice increases to the 1 temperature of -40 °C, at which point homogeneous freezing occurs.

Inductive ion capture: In a preexisting electrical field, there will be a separation of charge across a hydrometeor. As the hydrometeor falls, gaseous ions will either be attracted or repelled from the underside of the hydrometeor, depending on their sign. Thus, the hydrometeor will gain an increasing charge of whatever sign it has on its topside. In Fig. 1 the positive ions are repelled as the hydrometeor falls, but the negative ions are attracted. Thus, the hydrometeor gains a net negative charge as it falls. Figure 1: Inductive ion capture. 1 Ion capture may play a role in weakly electrified storms, but cannot be used to explain the amount of charge separation seen in a thunderstorm without the presence of other mechanisms.

  • Thunderstorm Anatomy and Dynamics
    THUNDERSTORM ANATOMY AND DYNAMICS An Overview Prepared by LCDR Bill Nisley MR 3421 • Cloud Physics Naval Postgraduate School • Monterey, California [email protected] Photo credits: Thunderstorm Cell and Mammatus Clouds by: Michael Bath; Tornado by Daphne Zaras / NSSL; Supercell Thunderstorm by: AMOS; Wall Cloud by: Greg Michels 1. Introduction The purpose of this paper is to present a broad overview of the various cloud structures displayed during the life cycle of a thunderstorm and the atmospheric dynamics associated with each. Knowledge of atmospheric dynamics provides for a keener understanding of the physical processes related to the “why and how” certain cloud features form. Accordingly, observation of cloud features presents visual queuing of changes in the atmosphere. 2. Thunderstorm Formation and Stages of Development Thunderstorm development is dependent on three basic components: moisture, instability, and some form of lifting mechanism. 2.1 Moisture – As air near the surface is lifted higher in the atmosphere and cooled, available water vapor condenses into small water droplets which form clouds. As condensation of water vapor occurs, latent heat is released making the rising air warmer and less dense than its surroundings (figure 1). The added heat allows the air (parcel) to continue to rise and form an updraft within the developing cloud structure. 2.1.1 In general1, low level moisture increases instability simply by making more latent heat available to the lower atmosphere. Increasing mid level moisture can decrease instability in the atmosphere because moist air is less dense than dry air and therefor is unable to evaporate • Figure 1 – Positive buoyancy / instability as a result of precipitation and cloud droplets as condensation and release of latent heat.

  • Charge Accumulation in Thunderstorm Clouds: Fractal Dynamic Model
    E3S Web of Conferences 127, 01001 (2019) https://doi.org/10.1051/e3sconf /201912701001 Solar-Terrestrial Relations and Physics of Earthquake Precursors Charge accumulation in thunderstorm clouds: fractal dynamic model Tembulat Kumykov* Institute of Applied Mathematics and Automation KBSC RAS, 360004 st. Shortanova, 89-а Nalchik, Russia Abstract. The paper considers a fractal dynamic charge accumulation model in thunderstorm clouds in view of the fractal dimension. Analytic solution to the model equation has been found. Using numerical calculations we have shown the relationship between the charge accumulation and the medium with the fractal structure. A comparative study of thunderstorm electrification mechanisms have been performed. 1 Introduction Convective clouds inside which thunderstorm processes mainly develop are natural objects with nontrivial fractal structure [1]. One of the most important thunderstorm parameters is the electric field intensity. Once a lightning strike have occurred, the electric field weakens and then recovers. The process of restoring neutralized charges and respectively the electric field after the thunderstorm discharge is the matter of animated debate among scientists. As is known, a central place in thunderstorm electricity occupies charge generation and separation processes inside convective clouds. About two dozen current mechanisms are known that result in charges generation inside the thunderclouds [2]. They can be divided into two groups. The first group is associated with elementary processes in the clouds:, the electrification within the ionic environment, the electrification caused by frictional contact between two icicles, the electrification accompanying the freezing of water and its solutions, the electrification upon destruction of crystallizing droplets, etc., The second group includes the induction electrification mechanism stipulated by the electric field, whose origin is not yet clear.

  • Evaluation of ISKA Forecast Performance
    Evaluation of ISKA forecast performance An investigation on binary and probabilistic forecast skill scores Björn Claremar, PhD Department of Earth Sciences Uppsala University Villavägen 16 SE-75236 Uppsala Sweden Uppsala, 12 March 2019 ii Evaluation of ISKA forecast performance Abstract The company Ignitia provides rainfall forecasts through SMS to subscribers in Ghana, Mali and some other countries in the West African region south of Sahara. Their ensemble-based probabilistic forecast product iska, based on the high-resolution weather model WRF with modifications, has been developed to better simulate tropical conditions where rainfall is driven by convection. This external investigation determined the forecast skill of iska by validating against NOAA satellite rainfall product. As comparison, rainfall probability forecasts from the global model GFS and from Weather Underground were evaluated. The iska forecasts outperformed the GFS forecasts and the Weather Underground forecasts in terms of accuracy. The statistical skill decreased towards the Sahel region and also towards the coast, the latter probably an artefact of the NOAA product having problems in identifying local warm-cloud rain, meaning that the forecast skill by the coast might be better than indicated. Keywords: West Africa, Ghana, Mali, Tropical weather, Weather forecast, Meteorology, WRF, rainfall, forecast skill, probabilistic, statistics, iska iii Executive summary Background Ignitia was seeking to evaluate the performance of its daily probabilistic rainfall forecasts through external party. The validation included making a comparison against baseline forecasts from NCEP (GFS), which is the most widely used source due to its free and public availability for commercial use, as well as data from a common online provider; forecasts from Weather Underground which is a subsidiary of The Weather Company, owned by IBM.
