Abstract:

Data from Unisys Weather was used to calculate tropical cyclone energy in the Atlantic, East Pacific, South Pacific, West Pacific, North Indian, and South Indian Oceans from 1996 to 2008. Trends in global cyclone intensity and frequency were studied. Furthermore, variables having short- and long-term effects on regional and global tropical cyclone activity such as the El Niño-Southern Oscillation (ENSO) were investigated. In most oceans, there was a distinct correlation between Tropical Cyclone activity and the ENSO anomalies.

The purpose of this research was to study hurricane activity. With the aid of satellite data from Unisys Weather, we studied hurricane tracks and tried to find a pattern in hurricane activity, such as, whether or not hurricane activity was increasing or decreasing over the years. We also tried to see how the hurricane season of one year differed from the hurricane season of another year. We also aimed to discover if hurricane activity in the A tlantic Ocean affected Hurricane activity in the East Pacific Ocean.

The interplanetary magnetic field (IMF) is a term used to describe the Sun’s magnetic field as it is carried by the solar wind into the space. The IMF is a vector quantity with three directional components, two of which (Bx and By) are oriented parallel to the ecliptic. The third component--Bz--is perpendicular to the ecliptic and is created by waves and other disturbances in the solar wind. The magnetic field of the Sun is produced by an electric current produced by consuming hydrogen to form helium at the interface and radioactive layers of the sun.The magnetic field produced is huge; it is about 50 Gauss and 100 times more than that of the Earth.

The solar wind is a stream of charged particles which are ejected from the outer atmosphere of a star or the sun's corona.

Some Useful Facts about Solar Wind:

+ contains a large number of electrons, protons, and a few ions
+ particles are able to escape through coronal holes because of the high temperature of the corona and the high kinetic energy of each particle
+ velocity varies from 200-889 km/s (with an average of about 450 km/s or 1,000,000 mph)
+ temperature of solar wind plasma around the Earth is about 150,000°K

The SEPICA (Solar Energetic Particle Ionic Charge Analyzer) is the prime sensor on the ACE (Advanced Composition Explorer).

We will be researching space weather and study how the solar wind affects the Earth's magnetic field and ionosphere.  We will be using ACE and SOHO satellite data for the solar wind, and ionosonde data for the Earth.

We are studying the solar winds effect on the Earth's ionosphere and magnetosphere. The sun emits charged particles, known as the solar wind. When these particles interact with the Earth's magnetic field the ion content of the atmosphere is affected. We have been analyzing data from the ACE (Advanced Composition Explorer) NASA satellite that measures the solar wind & this data is compared with measurements of the ionosphere. It has been found that strong gusts in the solar wind result in atmospheric Gamma ray bursts in addition to deviations in the electron content in the atmosphere
