what is the composition of the above mentioned sphere?
Nitrogen, oxygen, argon, carbon dioxide etc
Troposphere
 nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and small amounts of other gases
what is tropical storm arlene (1981)? It was a rare off-season tropical cyclone. what is the physical structure of this above type of cyclone just mentioned? Its formation was unusual, originating from a tropical disturbance that crossed from the eastern Pacific Ocean into the Caribbean Sea; few Atlantic hurricanes develop in this manner. what is the seasonal variation seen in this last mentioned hurricane? Approximately 97 percent of tropical cyclones that form in the North Atlantic develop between the dates of June 1 and November 30 and the official end has shifted from its initial date of October 31. what kind of intensity it has? It is determined by either the storm's maximum sustained winds or lowest barometric pressure. what are the steering factors of this hurricane? The surrounding flow throughout the depth of the troposphere, the atmospheric flow affects the path of a hurricane across the ocean etc

Troposphere [SEP] Composition
By volume, dry air contains 78.08% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and small amounts of other gases. Air also contains a variable amount of water vapor. Except for the water vapor content, the composition of the troposphere is essentially uniform. The source of water vapor is at the Earth's surface through the process of evaporation. The temperature of the troposphere decreases with altitude. And, saturation vapor pressure decreases strongly as temperature drops. Hence, the amount of water vapor that can exist in the atmosphere decreases strongly with altitude and the proportion of water vapor is normally greatest near the surface of the Earth.
