How Lightning Works?
Lightning transfers electrons from the atmosphere to Earth. Electrons build up in clouds because wind causes them to rub together (Charging by friction). The negative charges in…

Presentation on Hurricanes
Hurricanes are severe tropical storms that form in the southern Atlantic Ocean, Caribbean Sea, Gulf of Mexico, and in the eastern Pacific Ocean. Hurricanes gather heat…
How to Measure Precipitation?
Main objective of this lecture is to present on How to Measure Precipitation. Raingage – A cylindrical container that collects rainfall and measures its depth. Tipping-bucket gage –…
Mind Map
This article describe about Mind Map, which is a diagram for representing tasks, words, concepts, or items linked to and arranged around a central concept…
Snowflake Symmetry: Rotations and Translations in Nature
This lecture introduce on Snowflake Symmetry: Rotations and Translations in Nature. Snowflakes are all six sided because of their chemistry. They are made of water molecules. Water molecules are…
Lecture on Lightning
Principle objective of this lecture is to present on Lightning. The action of rising and descending air within a thunderstorm separates positive and negative charges. Water and ice…
Spectral Clustering
This article talks about Spectral Clustering, which is a techniques to make use of the spectrum (eigenvalues) of the similarity matrix of the data to…
What is Snow?
Snow falls from clouds that contain enough cloud droplets and ice crystals for precipitation to form. In order for snow to reach the ground without melting,…
Why Does It Rain?
When rain clouds are pushed up into cold air the rain drops form and become heavy enough to be pulled to the ground by gravity. Water…
Data Stream Clustering
Data Stream Clustering analyzes the advantages as well as limitations of data stream algorithms and suggests potential areas for future research. It faces many challenges…
Lecture on Rainfall Measurement
Major objective of this lecture is to present on Rainfall Measurement. Most rain gauges generally measure the precipitation in millimetres equivalent to litres per square metre. In this…
Types of Precipitation
Several types of precipitation exist and depend on the atmospheric temperature profile: Snow; Rain; Graupel and hail; Sleet and Freezing rain. Snow occurs from the Bergeron process, riming, and aggregation. The nature…
