Question 1: Is the weakening high? Reduce production? Drought?

Question 2:

Question 3: The precipitation is abnormal due to La Nina phenomenon, which is more than normal and lasts for a long time, and the urban terrain is relatively low;

Urban drainage facilities are poor.

Question 4: Remote sensing

Test analysis:

Question 1: This question examines the formation of the El Ni? o phenomenon. During the El Ni? o phenomenon, the trade winds in the southeast weakened, and the seawater temperature in the eastern tropical Pacific was higher than normal, which reduced the production of Peruvian fishing grounds. At this time, the western region is prone to drought disasters.

Question 2: This question examines the oak circulation. La Nina is the opposite of El Nino. The southeast wind trade winds are strengthened, and the seawater temperature in the eastern tropical Pacific is lower than normal. At this time, the western region is prone to floods.

Question 3: The main reason for the delay of floods around Bangkok is that La Nina phenomenon leads to abnormal precipitation, which is more than normal and lasts for a long time, and the urban terrain is relatively low; Urban drainage facilities are poor.

Question 4: This question examines the application of geographic information technology. The application fields of geographic information technology mainly include: the application of remote sensing in resource investigation, environment and disaster monitoring. So use RS technology.

Comments: This topic examines the application of geographic information technology. The application fields of geographic information technology mainly include: the application of remote sensing in resource investigation, environment and disaster monitoring (which can estimate production and help prevent and reduce disasters); Application of global positioning system in positioning and navigation (mainly used for in-situ positioning and navigation); The role of geographic information system in urban management (for urban information management and service, traffic road management, environmental management, urban planning, disaster prevention and mitigation, etc.). ).
