Pressure readings are taken at regular intervals (usually hourly) at weather stations. Weather maps are prepared four times a day at six-hour intervals. From these readings and maps, the changes in pressure can be observed and approaching weather forecast. If a low, for example, is approaching...
Understanding the impact of global climate phenomenon′s on an atmospheric branch of the hydrological cycle is crucial to make advances in skillful precipitation forecast. The present study adopts a multiscale approach based on wavelets for unravelling the linkages between teleconnections and atmospheric ...
CBS13 meteorologist Tracy Humphrey breaks down the weather situation across the state: Our forecast is scattered showers with isolated thunderstorms and... continued flood risk for Southern California as heavy rainfall courtesy of an Atmospheric River continues today and tomorrow.@GoodDaySac@CBSSacramento...
If the isobaric expansion coefficient and the isobaric heat capacity are known functions of temperature and pressure, then this equation can be integrated to calculate the potential temperature. Although in atmospheric science it is common usage to map specific entropy onto potential temperature, this ...
Satellite observation and Climate Forecast System Reanalysis (CFSR) are used to map the influence of the Agulhas current on local annual precipitation in Southern Africa. The pressure adjustment mechanism is applied over the Agulhas current region. Results unfold that the narrow band of precipitation ...
The 3D energy components are averaged over longitude to get the corresponding quantities in the 2D domain (latitude  pressure). Then we can average the 2D energy components over latitude with a weighting factor of cosine of latitude and integrate over pressure to get the global-average ...
Rising atmospheric vapour pressure deficit (VPD) associated with climate change affects boreal forest growth via stomatal closure and soil dryness. However, the relationship between VPD and forest growth depends on the climatic context. Here we assess Ca

4 and 5. These periods were selected because they represent particularly robust forecast improvement in the MAML model compared to the CNN. Figure 4a illustrates an anomaly map of geopotential height field at 300 hPa (Z300) and wave activity flux at 300hPa (WAF), along with mean sea-level ...
We conducted a series of 30-day DA cycle experiments, where we utilized 3-day forecast background fields initialized by ERA5. These background fields were combined with noisy observations of surface wind and upper-air temperatures at 50, 500, 850, and 1000 hPa pressure levels as models’ ...
