Interpreting A Synoptic Chart

2.

The air pressure at the centre of this cyclone is

1012 hPa
1020 hPa
980 hPa
1000 hPa

Correct Answer

A. 980 hPa

Explanation

The air pressure at the center of a cyclone is usually lower than the surrounding areas. This is because the air in a cyclone rises rapidly, creating a low-pressure system. The lower the air pressure, the stronger the cyclone. Therefore, a pressure of 980 hPa indicates a strong cyclone at its center.

The weather in Perth on this day is likely to be fine

True
False

Correct Answer

A. True

Explanation

The given statement suggests that the weather in Perth on this day is expected to be good or pleasant. This implies that there are no indications of any adverse weather conditions such as rain, storms, or extreme temperatures. Therefore, the answer "True" indicates that the weather in Perth is likely to be fine on this day.

Cyclones are linked with extremely high air pressures

True
False

Correct Answer

A. False

Explanation

Cyclones are actually linked with low air pressures, not high air pressures. In a cyclone, air spirals inward towards a center of low pressure, causing strong winds and stormy weather. This low pressure system is the opposite of high air pressure, which is associated with fair weather conditions. Therefore, the statement that cyclones are linked with extremely high air pressures is false.

The synoptic chart shows information that can be used to forecast the weather. This can be difficult, because there are a lot of different things that influence the weather. Even the experts sometimes get it wrong! There are a few rules that help. Rule 1: Highs normally mean hot days and cool nights in summer, and mild days and cold nights in winter. There will be light, or no wind, and clear skies. Lows mean stormy weather - strong winds, cloudy skies and rain, and usually mild temperatures. Rule 2: A cold front means a rapid drop in temperature and brings strong winds (and often rain) Rule 3: Isobars close together mean there are strong winds (because the air pressure is changing more rapidly in these areas) Rule 4: In the southern hemisphere, the rotation of the earth causes air to flow clockwise around low pressure cells, and anticlockwise around high pressure cells.

Cyclones are intense low pressure systems in the tropics associated with very strong winds. Cyclones form over oceans and sometimes cause great damage when they reach land. Describe the location of the tropical cyclone on the above map.
