Global Climate Change01:50

Global Climate Change

28.1K
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

Precipitation Processes01:12

Precipitation Processes

2.9K
The experimental conditions in a gravimetric analysis should be optimized to maximize the particle size and purity of the obtained precipitate. Ideally, the concentration of the precipitating reagent should be low with effective stirring to maintain low relative supersaturation for the growth of large crystals. In homogeneous precipitation, the precipitant is slowly generated by a chemical reaction in the solution to avoid local reagent excesses. For example, urea decomposes gradually to...

Precipitation Gravimetry

10.9K
Precipitation gravimetry is based on converting an analyte into a sparingly soluble precipitate, which is separated by filtration and weighed. An ideal precipitate should be pure, insoluble, of known composition, and easily filtered from the reaction mixture.
In determining nickel by gravimetric analysis, a precipitant of ethanolic dimethylglyoxime is added to a hot nickel salt solution. This is quickly followed by the dropwise addition of dilute ammonia solution until precipitation occurs. A...

What is Climate?01:16

What is Climate?

20.0K
Climate refers to the prevailing weather conditions in a specific area over an extended period. As the saying goes, “Climate is what you expect. Weather is what you get.” Climate is influenced by geographic factors, such as latitude, terrain, and proximity to bodies of water.

Econometric Views (EViews)01:29

Econometric Views (EViews)

377
Econometric Views, often stylized as EViews, is a package that merges statistical analysis with econometric studies. It is designed to provide tools for time series analysis, forecasting, and econometric model simulation. The software originated from MicroTSP software and has evolved significantly since its inception in 1981. The history of EViews is marked by a continuous effort to enhance its computational speed and user interface. It was initially developed for large computing systems but...

Freezing Point Depression and Boiling Point Elevation

Boiling Point Elevation
The boiling point of a liquid is the temperature at which its vapor pressure is equal to ambient atmospheric pressure. Since the vapor pressure of a solution is lowered due to the presence of nonvolatile solutes, it stands to reason that the solution’s boiling point will subsequently be increased. Vapor pressure increases with temperature, and so a solution will require a higher temperature than will pure solvent to achieve any given vapor pressure, including one...

Area of Science:

  • Climate Science
  • Oceanography
  • Computational Modeling

Background:

  • Sea-ice models developed for climate research offer valuable data for operational forecasting.
  • However, practical differences in scientific, software, and resource requirements hinder direct application.

Purpose of the Study:

  • To discuss challenges in applying research-based sea-ice models for operational forecasting.
  • To highlight new directions in sea-ice modeling for improved short-term predictions.

Main Methods:

  • Analysis of spatial and temporal scale discrepancies between research and operational needs.
  • Evaluation of model resolution requirements (e.g., >3 km for research vs. <300 m for mariners).

Main Results:

  • Research models may lack the necessary resolution for operational needs.
  • Critical Earth system feedbacks in research models might not be relevant at operational scales.

Conclusions:

  • Upgrades to atmosphere and ocean components of coupled models may be more crucial than sea-ice model enhancements for operational forecasts.
  • Promising new avenues in sea-ice modeling are identified.
